Density Ratio
 

hello,

in a high speed compressible flow where there may be shocks forming, what size density ratios might i get?

would these density ratios be bigger than i would get in a low speed combustion system?

thanks

Get an aerodynamcis or fluids book from your library, go to the supersonic chapters, and find some of the simple flows that can be solved analytically - with your electronic calculator (or slide rule).

Put some numbers in and calculate the density ratio (also pressure and temperature ratios) across a shock. And you can calculate the shock location. Now you have your answer - and the first test case for your code!

your answer is not overly helpful for a beginner in the subject ...

I disagree with you, Jim Park gave you the most correct answer, do your home work and learn the basics
