Hi to all, I am doing a steamflow simulation in vertical steel tube with diametre 12mm,,,,, reference pressure 60 bar,,,,, buoyancy ref density 33 kg/m^3, as with this pressure saturated steam density equal to it (as it is saturated flow, it is somekind of twophase flow, gas with water droplets),,,,, inlet 1m/s,,,, outlet static pressure 0bar,,,,,, So the results must show pressure drop with the length of tube, but it doesn't, even it shows excess,, in contrast, with waterflow in same conditions I get the pressure drop! Why there is no pressure drope, maybe with steam it should be like that, if yes please explane why, thank you.
