luckyXing is on a distinguished road
In the calculation of Fluent, the total pressure increases without external operation, but there is a point on the wall where the total pressure is higher than the total pressure of the incoming flow.(Not too much, inlet use pressure inet with total P = 9026.7Pa, Operating P = 0, total P at a point in the wall = 9026.86Pa)
and It's also curious that the formula for the total pressure-static pressure of an ideal gas should be related to the Ma number, Ma=0 on the wall, so the total pressure should be equal to the static pressure, but it's not;
