Week 2 - Flow over a Cylinder.

Aim: To find the optimal parameter of the fuel cell. Objective: To improve the performance of PEM fuel cells with Serpentine flow channel and single flow channel by varying the working parameters. To achieve uniform reactants distribution with lower fuel consumption. NOTE: Tool used to solve is COMSOL Multiphysics…

Project: Simulate the flow over the cylinder and the demonstration of the Von Karman Vortex. Abstract: Simulate the flow over the cylinder. Discuss the effects of Inflation addition layers and Effects of Reynolds number on the Coefficient of the Drag.   ------------------------------------------ Part-1: We will discuss…

Project: Steady Simulation of Mixing with Turbulence Modelling  Objectives: To perform Mesh independent study for the case Discuss the effects of the momentum ratio and length of the pipe To compare the `k-epsilon and k-omega` Turbulence Model Velocity and temperature line plots along and across the length of…

Aim: To compare the symmetry boundary condition vs Wedge boundary condition vs Hagen poiseuille's equation and obtain the comparing for angles of 10, 25, 45 degrees. Procedure: To compare the boundary condition first we need the get the analytical results from the Hagen Poiseuille's Equation. After that, we need to write…

Aim: Simulation of flow through a pipe in OpenFOAM:  In order to simulate the pipe flow in OpenFoam, we need to consider some of the factors like the computational power of the computer and simulation time of the problem. So, we divide the pipe for the small wedge, because it is easy to simulate the small position…

METHOD OF THE CFD: To solve the real-world problem, the people discovery three simples schemes for the numerical solution are  Finite…

Aim: To analyze and learn to use OpenFOAM and to solve the cavity problem for different grading factors and plot the velocity magnitude for the grading factor. To compare the velocity contour of the different grading factors. Procedure: Install Ubuntu OS on the computer and install the OpenFOAM in it. It is very easy to…

Aim:  To simulate 1D Super-sonic nozzle flow using the MacCormack Method Procedure: In order to simulate the nozzle flow, we must know the governing equation of the solving method. In this project, I have divided into different sections based on the process of the work. To simulate the equation, first, we need to…

Midterm 2D Heat conduction steady and unsteady state using the iterative solver. Aim: To find the No. of iteration on every solver and write a detailed report on it. Procedure: On solving the steady equation in heat conduction, we consider the there is no convection and No Internal Heat generation in this problem. Heat…

Taylor table: In this problem, we are going to calculate the error of the function by three methods. They are skewed right and left, central differencing. we are going to derive the second-order derivative of the given function and to calculate the fourth-order approximation of the given function. Given function for the…
