Fourth Order Approximation of Second Order Derivative using Central Differencing  We will derive the fourth order approximation for second order derivative using a taylors table method: The fourth order approximation uses four point nearby the point where we have to find the derivative , it can be seen in the following…

Steady and Unsteady State 2D Heat Conduction We will write a code for the steady and unsteay state 2D heat conduction  First consider the steady state heat conduction using implicit method : The code for the steady state implicit method is given below in the form of a function Here in this function we have three inputs…

Simulation of 1D supersonic nozzel flow using Macormack method Objectives:1. Steady-state distribution of premitive variable inside the nozzel.2. Time-wise distribution of premitive variables.3. Variation of mass flow rate distribution inside the nozzel at different time steps during the time marching process.4. Comparison…

Simulation of Backward Facing Step in OpenFoam: In this Challenge we are going to simulate an laminar-incompressible-viscous flow through a backward facing step geometry. For our Simulation we will use the tutorial problems given with the OpenFoam that uses laminar-incompressible-viscous flow. We can find this example…
