Aim: Perform transient state simulation on NACA 2414 Airfoil with varying Angle of Attack (AoA - `alpha`). Calculate the coefficient of Drag (`Cundersetd`) and Lift (`Cundersetl`) using time-averaged plot data of Drag force and lift force on the airfoil.   Objective: 1. Plot and calculate for 1, 5, 10, and 15 degree…

Aim: Setup a transient shock tube simulation; produce pressure, temperature plots, and mesh plots. Introduction and theory: 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…

Objective: Apply Reynold's decomposition to the NS equations and come up with the expression for Reynold's stress. Explain understanding of the terms Reynold's stress What is turbulent viscosity? How is it different from molecular viscosity? Theory: What is Turbulence? "Turbulence is an irregular motion which in general…

Aim: Setup a case in CONVERGE to perform Conjugate Heat Transfer simulation for a flow through a pipe.  Perform a Grid dependence test on 3 grids and discuss outlet temperature converging value. With baseline configuration, study the effects of Supercycle stage intervals on total simulation time. Show contour plots…

Shock Flow Boundary Conditions: Boundary conditions, which exist in the form of mathematical equations, exert a set of additional constraints to the problem on specified boundaries. The concept of boundary conditions applies to both ordinary and partial differential equations. There are five types of boundary conditions:…
