Relative humidity above 100%

    • ohernh


      I am using Fluent, with species transport, to simulate the mixing of air and water vapor. Both the air and steam enter the system at 100 C so the steam should't condense. My results show relative humidity above 100%. Does anyone know why that might be happening, or how I could fix this issue?

      It means you have too high a spaces concentration (vapour) for that temperature & pressure so the calculation thinks it ought to condense.  If it's only a 101% or so it could also be rounding error for when you worked out the species fractions on the boundary.
