shock wave calculation - 11/30/04 05:01 AM
Dear stress community,
I need some help for following problem.
I have to calculate a pipeline with liquid medium between a pump and an fast closing valve (simplified model), also a waterhammer calculation.
In the pipeline 4 heat exchangers are built in, to heat up the liquid.
To estimate the influence of the closing time I need to calculate the time of reflection in the pipeline. My question: what is the point where the travelling pressure wave will be reflected?
Have I to use the length between valve and heat exchangers
or
have I to take the assumption, that the pressure wave goes “through” the heat exchangers until to the pump and then back to the valve.
To solve my problem, I would like to get suggestions from “shock wave calculation” experienced engineers.
Thanks in advance …
