Surface tension and contact angle effects, negligible in larger tubes, were introduced in the extended method by including the Eötvos and Weber numbers. The proposed method seems to work relatively well based on comparisons against a broad database for air-water flow in round channels from 10 independent laboratories.

The effects of input temperature and compression ratio on the net output work and efficiency of the Atkinson cycle, Diesel cycle and Otto cycle are analyzed. It is assumed that the compression and power processes are isentropic and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ignored. The efficiency of these cycles is compared for equal maximum temperature as well. The findings may present guidance concerning performance evaluation and improvement of practical internal combustion engines.

Society cannot be created without the active contribution of women. In order to provide equal status in the society women need to be empowered. Policies on women's empowerment exist at the national, state, and local levels in many sectors, including health, education, economic opportunities, gender-based violence, and political participation.. Women can be empowered only when they are literate and educated. Education is the key to unlock the golden door of freedom for development. Of Indian women today, the female literacy levels according to the Literacy Rate 2017 census has been 87.95% where the male literacy rate has been over 95.56%. Being literate or having only primary education is not enough to enhance productivity or to obtain better-paying jobs but it is essential for women to pursue the higher education. Even beyond literacy there is much that education can do for women's rights, dignity and security. Empowerment of women is essentially the process of upliftment of economic, social and political status of women, the traditionally underprivileged ones, in the society. It is the process of guarding them against all forms of violence. The study is based on purely from secondary sources. The study reveals that women of India are relatively disempowered and they enjoy somewhat lower status than that of men in spite of many efforts undertaken by Government. It is found that acceptance of unequal gender norms by women are still prevailing in the society. The study concludes by an observation that access to Education, Employment and Change in Social Structure are only the enabling factors to Women Empowerment.

The concept of experimentally study of air conditioner, using earth air tunnel heat exchanger (EATHE) can be done to evaluate the performance of the system [6]. The ground can be used as a heat sink for cooling in the summer and as a heat source for heating in the winter. The air thus cooled or heated can be used directly for the conditioned space. The EATHE's are considered as one of the most passive system due to its ability to provide both the effects; heating in cold months and cooling during warm months. The aim of this work is to investigate the possibility of reducing the operational energy of typical house without negatively affecting its embodied energy. This is done through consideration of different building materials coupled with the use of an earth to air heat exchanger (EAHE) for fresh air supply and cooling. A single pass earth-tube heat exchanger (ETHE) was installed to study its performance in cooling and heating mode. ETHE consists of a 10.36 m long ½ inches diameter Aluminium and Copper pipe with wall thickness of 3 mm respectively. Fins are made of thin GI plate placed over the pipe and then spot we lded at several points. There are 25 fins per 0.5 m length of pipe. A 1 m wide, 3.19 m deep and 1 m long trench was first excavated by a bucket excavator Ambient air is pumped through it by a 400 w blower. Air velocity in the pipe is 11 m/s. Air temperature is measured at the inlet of the pipe, in the middle and at the outlet by thermistors placed inside the pipe. This arrangement can improve the Air Conditioning effect.

Swirling flow generates complex interaction between pressure gradients and fluid flow. To study the flow behavior and its effect in combustion chamber, experimental procedure is performed and recirculation zone is found out by using unsymetrical six vanes swirler.Here vanes used are of 45° at exit of swirler and 10° at inlet to the flow.To find out three dimentional velocities, five hole probe is used with multi tube manometer.To findout velocity at inlet duct anemometer is used. To validate experimental results, three dimentional flow within the flow geometry and through the swirler have been simulated by means of computational fluid dynamics(CFD) usind the code FLUENT Swirler applicable for producing CRZ (Central Recirculating Zone) to control length & stability of flame. Whole assembly design includes inlet pipes, Swirler, diffuser, expansion chamber, and tailpipe.The core objective of this study is to present the details of the experimental swirl flow. The flow through 8 blades at 45° rotating vane swirler is studied by using CFD Ansys. Present work gives complete behaviour and knowledge about recirculation zone & effect of guide vanes.

Swirling flow has large effect on flow field for getting stabilised and proper combustion intensity by controlling the mixing of the mixture. The core objective of this study is to present the details of the experimental analysis of an axisymmetric swirler model. Swirler with 8 blades at 45° rotating vane is studied experimentally. Also the effect of guide vane at different inlet and outlet angle on the rotating swirler is studied experimentally. An overlap angle of 30° is provided between the vanes for the proper guidance of the flow through swirler. A hemi spherical bluff body is attached to the hub in order to overcome the inlet flow field distortion. A five-hole probe has been used with traversing mechanism for measurement of flow. The recirculation velocities at the centre core and corner regions are well captured with the five-hole probe. Measurements along the entire length of the model at different stations, allow the determination of axial mean velocity component and pressure field parameters, which provide comprehensive information to aid and understand such complex recirculation flows. Flow field characteristics downstream of the swirler at different axial locations are examined in detail. The recirculation length and width are found to be strongly dependent on the amount of turbulence created by the vane swirler. Experimental analysis gives complete visualization of swirl flow with limits of boundary for mixing of flow.

The effects of input temperature and compression ratio on the net output work and efficiency of the Atkinson cycle, Diesel cycle and Otto cycle are analyzed. It is assumed that the compression and power processes are isentropic and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ignored. The efficiency of these cycles is compared for equal maximum temperature as well. The findings may present guidance concerning performance evaluation and improvement of practical internal combustion engines

Different flow patterns of air–water flow were observed simultaneously in the mini pipe at different values of air and water flow rates. Pressure drop prediction is investigated for vertical pipe in two phase flow. Pressure drop is causing more damage to vertical pipes as it has been many applications

Swirl flow offer an interesting field of study for aerospace & mechanical engineers in general and for combustion engineers in particular since it involves complex interaction of recirculation & turbulent mixing, which aid flame stabilization in combustion system. Swirling flow in both reacting & non-reacting conditions occur in wide range of application such as gas turbines, marine combustor burner, chemical processing plants, rotary kilns & spray dryers. Stabilization of flame can be achieved by various techniques. The most common techniques used in modern gas turbine combustors is swirl stabilization in which swirl velocity is imparted to inlet air using vane Swirler. Swirl can reduce combustion length by producing higher rates of entrainment of ambient fluid and fast mixing close to exit nozzle & on boundaries of recirculation zone in strongly swirling zones. Experimental studies show that swirl has lar...

The concept of experimentally study of air conditioner, using earth air tunnel heat exchanger (EATHE) can be done to evaluate the performance of the system [6]. The ground can be used as a heat sink for cooling in the summer and as a heat source for heating in the winter. The air thus cooled or heated can be used directly for the conditioned space. The EATHE’s are considered as one of the most passive system due to its ability to provide both the effects; heating in cold months and cooling during warm months. The aim of this work is to investigate the possibility of reducing the operational energy of typical house without negatively affecting its embodied energy. This is done through consideration of different building materials coupled with the use of an earth to air heat exchanger (EAHE) for fresh...

Swirling flow generates complex interaction between pressure gradients and fluid flow. To study the flow behavior and its effect in combustion chamber, experimental procedure is performed and recirculation zone is found out by using unsymetrical six vanes swirler.Here vanes used are of 45° at exit of swirler and 10° at inlet to the flow.To find out three dimentional velocities, five hole probe is used with multi tube manometer.To findout velocity at inlet duct anemometer is used. To validate experimental results, three dimentional flow within the flow geometry and through the swirler have been simulated by means of computational fluid dynamics(CFD) usind the code FLUENT Swirler applicable for producing CRZ (Central Recirculating Zone) to control length & stability of flame. Whole assembly design includes inlet pipes, Swirler, diffuser, expansion chamber, and tail...
