When does a ODE become unstable? --->     The ODE becomes unstable when we increase the time step(for explicit method only) for example in the python code below , an ODE is solved explicitly and the results are also shown below \"\"\" Explicit euler demo \"\"\" import math import…

[Part 2/2] Objective of the project: 1.The main objective of this project is to simulate the laminar flow through pipe. The wedge portion is taken as the whole circular section (cylinder) may take time to simulate or it may be costly if your computer do not have much resources. 2. The other objectives is to write the Matlab…

A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. By applying Newton\'s second law for rotational systems, the equation of motion for the…

#Objective of this challenge: To compare the Cell count , Outlet temperature and the number iteration for convergence for different cases with different length of tee and different momemtum ratios. #Introdution to Mixing Tee: Mixing Tee is also called as the T-joint because it splits the flow and the angle between them…

Introduction: A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate…

Give a brief description of why and where a CHT analysis is used. Conjugate heat transfer (CHT) refers to the coupling of conduction in solids with the convective and radiative heat transfer in the surrounding fluids. Accurately predicting CHT is an essential part of the design process. Conjugate heat transfer investigation…
