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

Introduction to Nozzle A nozzle is a device designed to control the direction or characteristics of a fluid flow (to increase velocity) as it exists (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid(liquid…
