Modelling and simulation of flow through a flowbench

A valve train in an IC engine is a mechanical system that controls the opening and closing of the intake and exhaust port. Its correct functioning is very crucial for running an IC engine properly. The valve train controls the valve timing, which affects the performance of the IC engine. The valve train consists of a camshaft,…

Objective: To determine the minimum cushion pressure needed to break different thickness of ice sheets using an air cushion vehicle with Newton Raphson method. Newton Raphson method is a root finding algorithm which produces successively better approximations to the roots (or zeroes) of a real-valued function. The most…

Objective To model piston assembly and do motion analysis for different wrist pin offset. Theory Piston is a part of the engine which reciprocates back and forth and convert linear motion into circular motion.
