AIM What are some practical CFD models that have been based on the mathematical analysis of Rayleigh Taylor waves? Explain how these mathematical models have been adapted for CFD calculations. Perform the Rayleigh Taylor instability simulation for 3 different mesh sizes with the base mesh being 0.5 mm. Compare the results…

ABSTRACT: Due to numerous reasons, improving fuel efficiency has become a very important topic for research nowadays. One of the ways to improve fuel efficiency is to reduce the drag forces encountered by moving bodies. For the prediction of drag forces, diversified approaches can be undertaken. CFD simulations provide…

Introduction: Otto cycle is nothing but a gas power cycle that is used in spark ignition(i,e petrol engine) for its working. It consists of 4 process: Isentropic compression Constant volume heat addition Isentropic expansion Constant volume heat rejection Objective: The Objective of this program is to find thermal efficiency…

OBJECTIVE:-1. To clean up the topological errors present on the given 5 types of models.2. To create a mid surface for the given models by using the manual method or the automatic midsurface creation method.3. Then the extracted mid surface meshes must have the following conditions for the quality meshcriteria.  …

OBJECTIVE: The objective of this project is to design and model an American chopper using solidworks and to assemble the parts and to create a photorealistic render of the chopper. INTRODUCTION : A chopper is a type of custom motorcycle perhaps the most extreme of all custom styles, often using radically modified steering…

ANSA is an industry-leading pre-processor software widely used in automotive industries.It is used to pre-process the geometry before a CFD or FEM analysis. INTRODUCTION: The aim of the project is to clean up the BMW M6 car model by removing itstopological errors. Further defining the different property ID\'s and also…

Conjugate Heat transfer Analysis: Conjugate heat transfer analysis is the simulation of the heat transfer between Solid and Fluid domains by exchanging thermal energy at the interfaces between them it is generally used when there is temperature variation during heating or cooling in the material due to the interaction…

OBJECTIVE : In this challenge, a structural mesh is performed (mid surface mesh), by cleaning up anauto motive’s hood assembly, consequently meshing the complete geometry with thetarget size (5mm) and quality criteria respectively. METHODOLOGY : Importing the CAD geometry which is a .stp file and is transferred to…

This following Matlab program is used to solve the forward kinematics of the 2R robotic arm manipulator. THEORY : Kinematics is the analysis of motion without considering the forces. Here, we need only geometric properties such as length and degree of freedom of the manipulator bodies. Forward kinematics refers to use…
