An Experimental Investigation of Palm Oil Blend with Diesel Fuel on Engine Performance and Emission of a Diesel Engine: A Review
Abstract: The main objective of this research work was to optimize the performance and emission of four stroke, single cylinder, indirect injection, water cooled diesel engine operating on palm oil and diesel blend. The use of vegetable oil as a fuel in diesel engine causes some problem due to their high viscosity compared with conventional diesel fuel. Various techniques and methods are used to solve the problems resulting from high viscosity. …

One Dimensional Thermal Model for Heat Flow in Friction Stud Welding
Abstract: Friction stud welding is a solid-state process in which the heat for welding is produced by direct conversion of mechanical energy to thermal energy at the interface of the components without the application of electric energy or heat from other external sources. Since it is thermal energy process, study of thermal behavior of dissimilar metals during friction stud welding process is important. Though there exist many thermal models for friction …

Numerical Simulation of Fluid Flow and Heat Transfer Enhancement in a Circular Wavy Channel
Abstract: The present study focuses on the computation of fully developed flow and heat transfer through a stationary circular wavy-walled duct. The fluid temperature at the channel inlet (Tin) is taken less than that of the walls (Tw). The governing equations are numerically solved in the domain by the control volume approach based on the SIMPLE technique. The circular wavy channel of 2.0 m length are tested in the current work; …
