## Prandtl Meyer Shock Problem

Objective: To visualize Prandtl Meyer expansion fan over an expansion corner using converge and understand the effect of SGS parameter on the shock location. Background: When a supersonic wave flows around a convex corner, a centred expansion occurs at the point of turn. This expansion consists of an infinite number Read more…

## Erosion in Cyclone Separator

Introduction: A cyclone separator is primarily an air pollution control device and is used to separate pollutant or any matter particles from air as it passes through it. Since the walls of the cyclone separator are continuously bombarded by particles, there will be erosion happening on the surface of the Read more…

## Shock tube simulation

Introduction: Imagine a calm pool of water. Now what do you think will happen when a stone is thrown in the centre of it? It will generate concentric ripples from the point of impact, right? This is what a shock wave looks like. In this project, we are going to Read more…

## Deriving the fourth order approximation of the 2nd order derivative

Introduction: In studies like numerical simulations and numerical methods, orders of approximation refer to how accurate an approximation is. The higher the order of approximation, the more accurate the value is. For example, a fourth order approximation value is more accurate than a first order approximation value. In this project, Read more…

## Transient simulation of flow over a throttle body

Introduction: In this project, we are going to simulate flow in an elbow joint that contains a throttle valve. This mechanism is widely used in carburettors and in the piping system in ships. In this project, we will study the flow patterns in the fluid due to the movement of Read more…

## Comparison of stress concentration on plates with different number of holes

Introduction: Does stressĀ  act differently on a structure depending on how many cuts or holes are present in it? Does a structure’s deformation depend on the number of cuts or holes present in it? To find out the answers, we will be designing two similar plates in this project, with Read more…

## Design of Frontal BIW enclosure of a car (Bonnet)

Introduction: The Hood or the Bonnet of a car is considered as the frontal BIW enclosure component. Bonnets are designed to reduce air resistance as the air flows around the car. The design of the bonnet is vital since it affects the aerodynamic flow around the car. Apart from this, Read more…

## Simulating flow through backward facing step

Introduction: Studying flow behavior through various structures is an important subject of mechanical engineering. When fluids flow through different geometries, they exhibit different velocity, pressure and flow properties. We have decided to simulate flow through a backward facing step to study the flow of fluids through geometries that have sudden-changing Read more…

## Crash Analysis of a Rear Car Door into a Pole

Introduction: When performing crash analysis, one of the common tests that engineers perform is check the integrity of the rear car door. In this project, we will perform the same test using a simulation. This project deals with analysis of a rear door of a car crashing into a pole. Read more…

## FSI analysis on the side view mirror of a car

Introduction: When a car travels through air, it basically pushes the air aside, causing the air to flow along the body. This flow of air along the car body impacts the forces acting on the car. The earlier models of cars which were box-shaped generated an increased amount of drag Read more…
