Week 4.2: Project - Transient simulation of flow over a throttle body
Project :- Transient simulation of flow over a throttle body
Aim:- The aim of the project is to simulate the flow through a throttel body using transient simulation. the objective is to
understand the development of the flow with the aid of different plots.
Theory:- The throttel valve arrangments which is the subject of this analysis is frequently used in automobiles to regulate the air fuel mixture in the combustion engine butterfly valves are the most commonaly used valves in this analysis we would be examining the results under the assumption of transient conditions.
Case Setup:-
The geometry that was used for the analysis is shown below An STL file was imported in to CONVERGE.it comprised of a number of open edges that were cleaned using a patch command
