In order to cool the cylinder, fins are provided on the surface of the cylinder to increase the rate of Heat transfer. By doing thermal analysis on the engine cylinder and fins around it, It is helpful to know the heat dissipation rate and Temperature Distribution inside the cylinder. We know that, By increasing the surface area we can increase the heat dissipation rate, so designing such a large complex engine is very difficult. The main aim of the present project is to analyse the thermal properties like Directional Heat Flux, Total Heat Flux and Temperature Distribution by varying Geometry(Circular, Rectangular),material(Aluminium Alloy, Magnesium Alloy) and thickness of Fin (3mm,2mm) of an approximately square cylinder model prepared in SOLIDWORKS-2013 which is imported into ANSYS WORKBENCH-2016 for Transient Thermal analysis with an Average Internal Temperature and Stagnant Air-Simplified case as Cooling medium on Outer surface with reasonable Film Transfer Coefficient as Boundary Conditions.

Even though there is such an importance for technology in our routine life there are even people whose life styles are very far to this well-known term technology. So it is our responsibility to design few reliable systems which can be even efficiently used by them, farmers. The farmer who toil and does hard work to produce the crop suffers a lot at the end. The factors include unexpected rains when yielded crop is dried before selling, which will completely destroy the crop yield or make the yield second grade. To avoid such condition, automatic rain protected drying sheds are to be developed. In this project, we propose a system in which the rains are detected automatically and protective shield is wrapped on the rooftop sensor an intelligent microcontroller and a DC motor are employed. The rain sensor of such drying shed which protect the crop against rain and getting wet. To automate this task, a rain senses the rain and data is passed to the microcontroller. The microcontroller processes the data and activates the DC motor control circuit and a protective wrapper is wrapped on the roof top.

The automobile industry has shown Increased interest in the replacement of steel leaf spring (55 Si 7) with composite leaf spring (E-glass/Epoxy) and Jute/ glass epoxy due to high strength to weight ratio, Higher stiffness, high impact energy absorption and lesser Stresses. This research is aimed to investigate the suitability of natural and synthetic fiber reinforced hybrid composite material in automobile leaf spring application. By using natural fibers efforts have been made to reduce the cost and weight of leaf spring. In this work an attempt is made to develop a natural and synthetic fiber enforced hybrid composite material with optimum properties so that can replace the existing synthetic fiber reinforced composite material n automobile leaf spring. Jute and E-glass woven roving mats are used as reinforcements and epoxy resin LY556 is used as the matrix material. The CAD models of Leaf spring are prepared in CATIA V5 and imported in static structural analysis work bench of Ansys14.5 where ignite element analysis (FEA) is performed. The design constraints are stresses and deflections. This study gives a comparative analysis between steel leaf spring and Jute/E glass reinforced Epoxy leaf spring. The hybrid composite leaf spring is found to have lesser weight, lesser cost, lesser stresses and higher stiffness.
