Summary

In this tutorial, the cavitation characteristics of a hydrofoil is investigated and compared to experimental data. The capability for multi-dimensional simulation of cavitating flows is of critical importance for efficient design and performance of many engineering devices. Cavitation refers to the formation of vapor filled cavities at low pressure regions of a flow field and their subsequent implosion while passing through high pressure regions of the flow field. Their phenomenon generally is undesirable causing erosion of propellers, pumps and other solid bodies. They are however considered and used in a beneficial way for a number applications including ultrasonic cleaning, water purification, high speed underwater propulsion and even to produce high temperatures and pressures for initiating thermonuclear fusion reaction. 

Detail

This tutorial uses the cavitation module available in CFD-ACE+ and gives quick startup instructions on the following topics.

  • Importing a grid file into CFD-ACE+.
  • Setting model properties (Cavitation properties).
  • Setting problem type.
  • Setting volume/boundary/initial conditions.
  • Setting solver control properties.
  • Requesting printed and graphical output.
  • Submitting model to obtain a solution.
  • Checking for solution convergence.
