 September 7, 2008, 09:11 Educational example for velocities #1 Sergio Guest   Posts: n/a I need to prepare or to find, for educational purposes a, so smal as possible, source code (Delphi, Pascal or Fortran I can understand) which enable to estimate the velocity of the AIR (modulus) at the 12 points indicated in the figure I put at internet address http://www.cognitor.com.br/AirVelocity.jpg The input variables are the velocity V at the input window (pressure = 0 at the exit window)and A, B and C dimensions showed in the figure ? Errors up to 20 % are acceptable . Can you help me indicating where to find it ? Thanks in advance

An Introduction to Computational Fluid Dynamics by Verstegg and Malalasekera is an excellent reference. Good Luck Scott

I have this book and others but I did not succeeded to arrive to a real code A "small code" which solve my problem will also enable me to see how to mount an algorithm using SIMPLE or SIMPLEC or other. Do you know where I can find this ?

I believe there is a Matlab code there that is similar to what you want. The site is http://ta.twi.tudelft.nl/users/wesselin/ Good Luck Scott

Errors up to 20 % are acceptable . Can you help me indicating where to find it ? Thanks in advance The impressive thing is that it seems to be easy to solve but I could not find any written solution for this in the last two years.
