Modelling and simulation of flow through a flowbench

OBJECTIVE:

• To a Perform a Grid dependency test for a particular valve lift
• Perform a parametric study to determine the effect on the mass flow rate with different valve lifts
• Plot velocity cutplot for different valve lifts.

PROCEDURE:

• Draw the Circle

• Do the Boss Extrude

• Draw the Intake Port

• Then the shell commend

• Then create a valve
• To create valve first create the axis
• Then create the plane
• Create sketch on the plane
• By using revolve option we create the valve

Flow Simulation:

• Wizard

• Project name

• Analysis Type - Internal

• Type of Fluids - Air
• Flow Type - Laminar and Turbulent

• Boundary condition at inlet

• Boundary condition at outlet

• Then apply the global mesh at (5,6,7)

• Goals - SG mass flow rate

• Cutplot - velocity

• Adding flow trajectory

Result:

Mesh at 5

Mesh at 6

Mesh at 7
