 December 1, 2006, 09:58 Static and Total Temperature #1 Tomislav Guest   Posts: n/a I am simulating the heating and natural convection of Heavy Fuel Oil in a tank. I obtain different values for Static temperature (300 to 420 K - the expected range between boundary temperatures) and Total Temperature (300 to 326 K). Shouldn' t Static and Total Temperature be equal if the maximal velocity is 0.005 m/s? How can I explain it?

That's why I am wondering about the difference between static and total. The velocity is 0.005 m/s, I think it is too slow to have such different total and static temperature
