Week 4.2: Project - Transient simulation of flow over a throttle body

Aim: Transient simulation of flow over a throttle body.

Procedure:

Load the case setup file for steady state flow and make the following changes.

In run parameters select the transient solver

In Simulation time parameters, End time is 4*time for flow to take place through the pipe=4*vel*char length=0.01 secs.

 Now go to boundary and for throttle , Select boundary type as wall and wall motion type as rotating.

 

 To get the centre point of the valve rotation,

Go to measure> Direction > Arc Normal select three points and click apply.

Copy the arc centre coordinates.
