Assessment of Engine Performance with Perforated and Solid Fins
Abstract: Abstract Fins increases the heat transfer from a heat generated device by increasing the surface area of it. Fin with holes or perforated fins increases the surface area available for heat removal but also increases the intensity of the air flow, which further increases the heat removal. A two wheeler engine with fins having circular perforation has been designed in the present work. ANSYS 16.0 has been utilized to solve …

Performance Evaluation of an Arbitrary Profiled Vertical Fin in Non-Newtonian Medium
Abstract: Abstract In this article, the problem of a parabolic profiled fin dissipating heat by natural convection to quiescent non-Newtonian fluid has been solved theoretically. The generalized equations of temperature distribution and heat transfer rates have been generated using the appropriate boundary conditions with different flow behavior index (n). The results obtained from the graphs indicated that there is a significant influence of flow behavior index (n) and fin parameter (M) …

Influence of Process Parameters on Temperature Distribution and Microstructure of Friction Stir Welded Magnesium Alloy
Abstract: Abstract The effect of processing parameters on temperature distribution and microstructure was evaluated after friction stir welding of AZ31 magnesium alloy plates. Temperature distributions were recorded using thermocouples inserted into the drilled holes. Microstructures of the specimens were evaluated using optical microscopy and grain size and other factors were measured. Microhardness results were evaluated using Vicker’s micro hardness tester. Microstructure results revealed that grain size was reduced and grain structure …

Thermal Performance Analysis of a Solar Dryer-cum-Air Heater with Modified Absorber Surface
Abstract: Abstract The use of solar resource for food drying has always been a food preservation technique which has widely been practised in most parts of the world. The solar drying system utilizes solar energy to heat up air and to dry food substance placed in dryer, which is beneficial in reducing wastage of food products and helps in preservation of the same. Unfortunately, some of the methods practised in the …

Thermal Analysis (Energy and Exergy) of Crystalline Silicon Solar Photovoltaic Module for Hazy Day
Abstract: Abstract With the growing population, demand for a renewable energy source has reached to peak level. It is necessary to have that source available easily and in sufficient quantity so that with the diminishing non-renewable source, basic need of energy can be fulfilled. This source can be the all-time available source, ‘solar energy’. Concern of most of the countries is just to make the availability of this source better and …
