Objective: To simulate flow over an NACA 2412 Airfoil and calculate drag co-efficient and Lift Co-efficient at different angle of attacks (1⁰, 5⁰, 10⁰and 15⁰) to compare the drag co-efficient and lift co-efficient for all angles of attacks and compare the effect of turbulence models. Introduction:  An airfoil…

Objective: To perform external flow simulation over an Ahmed body and validate the results with experimental data. Introduction: As the burning of fossil fuels becomes a more pressing issue, manufacturers are introducing more fuel efficient cars to the market. One main contributor to fuel burn is the car’s aerodynamic…

Introduction:     In a traditional spark ignition gasoline engine, the throttle body is the part of the air intake system that controls the amount of air that flows into an engine\'s combustion chamber. It consists of a housing unit that contains a throttle plate (butterfly valve) that rotates on a shaft.When…

Introduction:       Flow over a backward facing step forms the basis of many real flow situations. It is often used as test cases for improvement of numerical schemes and is a classical problem in applied aerodynamics. The backward-facing step is a common test case for CFD codes. Although the geometry is…

Introduction: To regulate the power output from an engine, there has to be some restriction of fuel - air mixture that reaches the cylinders. One way to do this is to use some kind of valve that restricts the air, fuel is then regulated to get the correct fuel – air mixture. The most common valve is of butterfly…

Objective: To setup a transient shock tube simulation and plot the: Pressure and temperature history in the entire domain Cell count as a function of time. Introduction: Shock tube is a device which is used to produce and confine shock waves. It contains a diaphragm that separates a high pressure and a low pressure section.…

Objective: To visualize Prandtl Meyer expansion over an expansion corner using converge and understand the effect of SGS parameter on the shock location. Introduction: Shock Wave: In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than…

Objective: Simulate flow through a solid pipe and understand the effect of Super-Cycling Introduction: The term conjugate heat transfer (CHT) is used to describe processes which involve variations of temperature within solids and fluids, due to thermal interaction between the solids and fluids. The exchange of thermal…

OBJECTIVE: To clean up the geometry, flag the boundaries, create a virtual wind tunnel, and perform aero simulations for the FSAE vehicle to calculate the total downforce on individual components. INTRODUCTION: Race cars, in general, have a peculiar shape that distinguishes it from any road car on the planet. This shape…

OBJECTIVE: To solve steady and unsteady 2D heat conduction equations using different iterative techniques for implicit and explicit methods in MATLAB. PROBLEM STATEMENT: 1. Assume that the domain is a unit square.  2. Assume nx = ny [Number of points along the x-direction is equal to the number of points along…

OBJECTIVE: This project's main aim is to perform numerical-solution analysis of a Quasi 1D Supersonic Nozzle Flow using the Maccormack Method. Although analytically identical, the numerical solution of conservation and non-conservation forms of the governing equations is usually different. That is the reason…
