Getting started with Flow SImulation in SolidWorks

PIPE FLOW SIMULATION & PARAMATRIC STUDY WITH LINE PROBES USING SOLIDWORKS

1. Create a cylinder model: size -Dia=120mm, Length = 1meter.

2. Convert to shell of thickness 2mm

3. Draw line probes at 0.95m, 0.9m and at 0.85m from top / inflow.

These line probes are created to check velocity, shear stress at this particular sections of the pipe flow.

4. Save as pipe_flow_with_line_probe.sldprt

5. Go to Flow simulation. Create Lids on both inlet and outlet of pipe.

Origin point is inlet & other end is Outlet where line probes are created.

6. Save file as pipe flow with line probes. Create wizard with internal flow and water as flow medium.

7. Apply Boundary conditions: Inlet Velocity = 20m/sec, outlet pressure as 101325Pa, Create Ideal wall.

Flow simulation model is ready.

8. Create mesh manual with x=10, y=10 & z= 100.

9. Run the flow simulation.

10. Post Processing:

a) Create x-y plots at 95%, 90% and 85% length of pipe, comparison of velocities at all three line probes and View the results.

b) Velocity profile at 95 percent length:

c) Velocity profile at 90 percent length:

d) Velocity_profile_85percent:

e) Comparision of Velocity profiles at 95, 90 & 85% lengths. Plot shows same velocities through all three cross sections:

All Velocity plots are satisfactory.

f) Create a cut plot and view the velocities at cut three sections of pipe.

11. Parametric Study:

Create new parametric study with design points of different no. of mesh cells and velocities. Provide input variables and output parameters required. Details are shown in following figure.

12. Run the Flow simulation again.

13. Cut Plot Contours at 95% length are as below and satisfactory.

a) cut_plot_vel_95percent_Design Point 1:

b) cut_plot_vel_95percent_Design Point 2:

c) cut_plot_vel_95percent_Design Point 3:

d) cut_plot_vel_95percent_Design Point 4:

14. Completed.
