Robert Caulk posted a new comment: Ah, I think I understand now. You are saying that the only approximation is the constant viscosity. I was just saying the change of viscosity of geofluids as a function of pressure is small enough in the liquid phase at a constant temperature that it is OK to neglect it. This is why I say we are assuming constant temperature with our constant viscosity assumption. But this is likely what you were getting at when you mentioned that this model is inappropriate for gases earlier. I also now realize that the change of fluid density at low mach numbers is negligible too, so it seems the scheme is actually accurately considering all possible compressibility given the aforementioned assumptions. I guess it would be futile to try and gain accuracy by considering these small changes to viscosity within the pore throats without considering full convective and conductive heat transfer in the system. >Which equations do you have in mind for compressible flow between parallel plates? Honestly, I need to spend time looking into the options. But my preliminary search was pretty bleak a couple weeks ago. Thank you for taking the time to explain these details to me.
