Pressure & Bernoulli's equation
Hi, frineds,

I am studying wind environment around buildings by Fluent. After convergence and y+ was less than 150, why was the static pressure of some point at windward wall larger than the totoal pressure(dynamics pressure) of the point at the same height of the inlet? According to Bernoulli's equation, it should be lower. Could you tell me the possible reason?

Many thanks, Justin

Re: Pressure & Bernoulli's equation
From the previous thread, it looks like related to pressure gradient. Make sure the y+ is near to 1 and use enhance wall function. refine the intersted wall. even use LES model. Any comment?
