The Linear Convection Equation arises from the Navier-Stokes equation wherein we consider only the convection terms for the x component of the velocity. This equation represents the propagation of a wave without change of shape; the speed of the wave is C. This means that on an axis with the positive direction to the right,…

Interpolation Schemes: The approximation of surface and volume integrals may require values of the variables at locations other than the computational nodes of the CV. Values at these locations are obtained using Interpolation Schemes. Some of the commonly used interpolation schemes are: a) Upwind Interpolation Scheme …

Steady-State Simulation of Fluid Flow over a Throttle Body The aim of this project is to perform a steady-state simulation for fluid flow through a throttle body.

CONJUGATE HEAT TRANSFER SIMULATION The term conjugate heat transfer is used to describe processes which involve variations of temperature within solids and fluids, due to thermal interaction between the solids and fluids. In this study, fluid flow through an aluminium pipe was considered to perform the Conjugate Heat Transfer…

Pendulum Motion Analysis The purpose of this project is to solve a second order differential equation which governs the motion of a simple pendulum. The motion of pendulum depends on the Newtons Second Law and follows the second order ODE given by:     In the above equation, g = gravity in m/s2, L = length of…

INTRODUCTION The aim of this project is to determine the numerical solution of a 1-D Supersonic Nozzle Flow using the Macormack method. Both Conservative, as well as Non-Conservative Approach, are discussed in this project. Although analytically identical, the numerical solution of both these approaches tends to vary a…
