How to do Howarth–Dorodnitsyn transformation
 

Hi everyone, I am now doing Howarth–Dorodnitsyn transformation from the compressible form to the incompressible form.

For example, from the conservations in the compressible form with the variables, how to get the incompressible form? I am confused with the detailed derivations of formulas.

Thank you

I attach two pages from an italian Gasdynamic course, I hope you can understand

Thank you Filippo. Actually it hard for me to read Italian. But I will try to figure out the equations. Besides, do you have some other materials about it?

have a look here
