In this project, we will write computer programs to manually determine the Eigen Value and Spectral Radius of the given system of equations. Also, solve them using iterative techniques like JACOBI, GUASS SEIDEL, SOR. The linear systems given are: `A=((5 ,1, 2) , (-3, 9, 4), (1 ,2, -7))` `X=((x1),(x2),(x3))` Computing…

What is Discretization? The general idea behind discretization is to break a domain into a mesh, and then replace derivatives in the governing equation with difference quotients. The discretization process is used to solve different PDE's, by changing them into algebraic terms.   Following code is written to…

Objective: The objective of this test is to simulate the steady-state airflow through a Prandtl Meyer Expansion Fan by using Converge CFD.    What is Shock Wave? Like an ordinary wave, a shock wave carries the energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change…

Objective: The objective of this project is to perform a shock tube simulation using Converge CFD.  Introduction: The shock tube is an instrument used to replicate and direct blast waves at a sensor or a model in order to simulate actual explosions and their effects, usually on a smaller scale. Shock tubes…

In this project, we will look to solve Steady and Unsteady 2D heat conduction problem using point iterative solvers such as JACOBI, Gauss-Seidel, Successive Over Relaxation (SOR) methods. For solving the Steady-state equation of 2D heat conduction: `(del^2T)/(delx^2)+(del^2T)/(dely^2)=0` Therefore by Central Differencing,…

WHAT ARE ODE( Ordinary Differential Equation)? In mathematics, an ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and the derivatives of those functions. The term ordinary is used in…

Objective: To calculate the total downforce for the individual components of cars and any improvement in the components.  Aerodynamics Components: A Formula One race car is defined as much by its aerodynamics as it is by its powerful engine. That's because any vehicle travelling at high speed must be able to do two…

LINEAR CONVECTION: This equation is the most accessible equation in CFD; from the Navier Stokes equation we kept only the accumulation and convection terms for the x component of the velocity - as we already know, in CFD the variables to be computed are velocities; to make things even simpler, the coefficient…
