Modelling and simulation of flow through a flowbench using SolidWorks

• Grid Dependency Test:-In grid dependency test three different mannual global mesh is used as given in table

	Case-1	Case-2	Case-3
Nx	30	60	120
Ny	30	60	120
Nz	12	24	48

1. For Case-1 Velocity Cut Plot:-

2. For Case-2 Velocity Cut Plot:-

3. For Case-3 Velocity Cut Plot:-

• Conclusion

Comparing the above three figures,we can see the third case shows a better results in terms of velocity variation,So third case is chossen for further analysis.

Effect of valve lift on mass flow rate

VALVE-LIFT(in m)	MASS FLOW RATE
0.001	-0.17505
0.002	- 0.31334
0.003	-0.45402
0.004	-0.5931
0.005	-0.71367
0.006	-0.83103
0.007	-0.90207
0.008	-0.96003

* negative sign shows that mass is leaving from the system
