Question about comparison between CFD results and experimental data

idomeneo · January 30, 2015, 04:36

Hi everybody,
my question is not properly about CFD but mainly about Fluid Dynamics itself. I have performed a RANS simulation of a round free jet of methane and air and now I'd like to compare those results to some experiments. Unfortunately there aren't papers about experimental data for methane/air jets but mainly I'm finding a lot of data about round jets of water with different nozzle dimensions. So my question is: can I compare those experimental data with my results if the Reynolds number are the same? Or is it highly incorrect?

Thank you guys!

Try modeling the problems in the paper involving water first just to gain some confidence. Then you can start thinking about how the two problems are different.

Hi,
How can i compare my cfd results with experimental data? Now i am having cfd results. And also i am having experimental paper ..i dont know how to extract those data.
