ziemowitzima Senior Member Mieszko Młody Join Date: Mar 2009 Location: POLAND, USA Posts: 145 Rep Power: 18	Dear Foamers, I am modeling a "simple" case, flow from high pressure tank (1bar, 300K) to a low pressure tank (10Pa, 70K) through a hole. The flow behaves "more/less" in a consistent way, but there is a very high temperature increase at the "head of the pressure wave". Please see attached figures. Is it physical ? Or it is some numerical artifact ? T_0p005sec.jpg vel_0p005sec.jpg p_0p005sec.jpg
