pressure fluctuations
pressure fluctuations
(OP)
Hallo
does there exist any procedure or equation which enables to calculate pressure fluctuations in turbulent flow.
I need some simple formula which can fastly predict pressure fluctuations in flow. Only for estimation purpose!
thanks

RE: pressure fluctuations
Perhaps you are not talking about the transient random variations in fully turbulent flow and you mean the flow profile which would affect the total pressure (dynamic + Static).
It might help if you explained what you are trying to do and why.
RE: pressure fluctuations
I am doing some dosing of fluid into process chamber, for what I am using the backpressure regulator. Since the flow in those two chambers must be constant I am triing first just to predict weather the pressure floctuations will be high or not. Actually I am trying to find some simple procedure or rule of thumb which would tell me how high are the pressure floctuations during some fluid dosing in pipes. I do not want to do this cfd stuff since it not so important,...so does there exist some estimation which could tell me the amplitude of those pressre floctuations in pipes only by knowing the pipe diameter, pressure and velocity btw flow of fluid!thanks,...

We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer
