Getting started with Flow SImulation in SolidWorks
AIM:
Study the Pipeflow Simulation and compare the normalized velocity at different line probes of the pipe length.
OBJECTIVE:
- Run the Pipeflow Simulation on a pipe of certain dimension parameters.
- Study the normalized velocity at line probes 0f 85%,90% and 95% of pipe length.
- Compare the normalized velocity at the line probes with the inlet velocity with plots.
- Follow the process for fluids with Reynold's number 100,1000,10000.
- Conclude the results.

The observatory proves that the velocity of air at line probes of different probe length occurs steadier with increase in distance from the inlet surface.The velocity comparison with the inlet velocity proves to show significant difference in the range of air velocity along the diameter.The inlet velocity remains almost steady to its in the middle with decrease in velocity on reaching the ends of the diameter.
The XY plots of velocity at different line probes provide a initial constant rising curve followed by a constant decreasing curve with self satisfying second order continuity.The point of maximum velocity at each probe appears to occur at almost the center of the diameter.
The plots conclude the signifance and dependence of the Reynold's Transport Theorem.
From the plots, the velocity of the system increases with the increase in Reynold's number with due respect to increase in the inlet velocity of the system.The cut plot provides information the variation of velocity parameters.The velocity variation appears uniform in the plots with only the change the respective velocities for their respective Reynold's number
