Hi everybody, my question is not properly about CFD but mainly about Fluid Dynamics itself. I have performed a RANS simulation of a round 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!
