Adarsh Guest Posts: n/a	Hi all, I want to model H2 flow through a microchannel. I am feeding the channel at 25 psi and exit is at atmospheric. There are several bends. I would like to model this flow. Should I use the Euler equation or the compressible Navier Stokes? Which one gives a better predictions? i calculated the velocity using an experiment measuing the volumetric flow rate, the average velocity seems to be 60 cm/s, which is well below the Ma number of 1320 m/s in hydrogen. thanks, Adarsh.
