Modelling and simulation of flow through a flowbench

FLOW THROUGH FLOW BENCH

AIM
To create a 3D model of a flow bench and run flow analysis.
To conduct grid dependency test and select the best grid.
To run a parametric sweep tp show the effects of valve lift on mass flow rate.

SIMULATION
The model is done as per video.
The initial valve distance is set at 0.003m.
The grid dependency test is done with 3 levels of refinement-2, 3, 4.
Choose the grid with best results(here 4).
Do parametric study with input as valve distance and output as mass flow rate.
Run for 7 different values.
Plot the results in graph.
Static pressure= 101325 Pa
Total pressure= 151325 Pa

GRID DEPENDENCY TEST @0.003m
LEVEL 2

LEVEL 3

LEVEL 4

RESULT

CONCLUSION
It is observed that we get better results in level 4 refinement in grid dependency test. The mass flow rate increases(-ve denotes mass leaving) as the valve lenght increases.
