To simulate the isentropic flow through a quasi 1D subsonic-supersonic nozzle: subsonic-supersonic nozzle to be solved using two form.  They are conservation and non-conservation forms. Conservation form equation: ∂(ρ’A’)/ ∂t’ + ∂(ρ’A’v’)/ ∂x’…

Mesh specification Number of cells along the x direction (longer dimension) = 200 Number of cells along the y direction = 10 Use a graded mesh. Grading factor near all walls should be 0.     First the geometry has to be created.  So the apprapriate solver is choosed and geotmetry is created in the blockMeshDict…

Simulation of Flow through a pipe:       Assume that water at temperature 303K, flowing through a pipe of 10mm diameter with a laminar flow of Re=2000. we need to find the entrance lenght(le), lenght of pipe(l), average velocity(Vavg) and pressure drop using Hagen poiseuille's equation.  …

    Using the values from  previous challege, leght of pipe is 5mm and average velocity is 0.1602m/s. This matlab program will provide the geometry file for any wedge angle. thus it needs the angle as input. Matlab Program for different wedge angle: clear all close all clc wedge_angle = input('enter the…
