Week 7 - Simulation of a 1D Super-sonic nozzle flow simulation using Macormack Method

Conjugate Heat Transfer analysis on Exhaust Port   Aim : To simulate the flow of hot exhaust gases through an exhaust port and see how the heat transfer takes place and verify the same.  Introduction:  Conjugate heat transfer co efficient refers to accurately predicting heat transfer between the…

AHMED BODY Aim :  The aim of this project is to find the drag and lift co-efficient of the flow over the ahmed body and validate it by comparing the results to experimental results. Also to do a grid dependency test to fiugre out the optimal meshing set up. Introduction to AHMED BODY:    The Ahmed Body was…

Aim:  The aim of this project is to study a two dimensiona flow of a user specified fluid over a 2-D cylinder on a plane for varying Reynolds number.    Introduction:  When a fluid is made to flow over a cylinder vortex is produced. A vortex is in the process of formation near the top of the cylinder…

AIM The main aim of this CFD simulation is to determine the factors affecting the mixing efficiency of 2 fluids at different temperatures through a tee section using ANSYS Fluent and comparing the results    MODEL The image below shows the model of the tee through which of which the mixing efficiency is simulated.…

Objective : To compare the results of the flow simulation through an open pipe in wedge condition (considering wedge angle `theta` = 1,3,4) and symmetrical condition for (`theta` = 10,25,45) with the results obtained from the analytical solution using Hagen-poiseuille's equation. Let the length of the pipe be - L…

Flow through a pipe in OpenFOAM Principle:  The flow through a pipe works on the basis of Hagen–Poiseuille Equation which is a fluidic law to calculate flow pressure drop in a long cylindrical pipe and it was derived separately by Poiseuille and Hagen. Here let us consider a incompressible Newtonian fluid…

Finite Volume Method(FVM) : It is a method for representing and evaluating partial differential equations in the form of algebraic equations. In the finite volume method, volume integrals in a partial differential equation that contain a divergence term are converted to surface integrals, using the divergence theorem.…

BlockMesh drill down Boundary condition specifications:  The given boundary has to be meshed and flow inside should be simulated in openFOAM. The boundary is divided into 3 blocks as we can see in the figure below. The dimensions are as follows : The width along the z-axis does not matter since the simulation we are…

Simulation of a 1D Super-sonic nozzle flow simulation using Macormack Method   Introduction  Let us consider a quasi 1-D flow through convergent divergent nozzle which is initially at subsonic speed and exiting at supersonic speed. The flow is along the direction of x axis making it one dimensional flow. All…
