Pressure waves in 32" Pipeline
Pressure waves in 32" Pipeline
(OP)
Hello everybody,
I am doing dynamic stress analysis of 32" Diesel pipeline. Due to the closure of a ball valve, a fluid hammer travelling backwards is generated. The pipe has many vertical loops and horizontal direction changes. Now, my question is: what happen to the pressure wave when it hits such vertical and horizontal direction changes (imagine elbows)? I'm quite sure there will be a new wave travelling on the opposite direction, towards the ball valve. But what about the original one? Will continue its travel even going upwards or left or right? And if yes, will it be mitigated somehow?
Thank you

Independent events are seldomly independent.

Just think of a wave going along an open square channel - it will continue round a smooth bend with a bit of back wash, but not much. Only when it hits a solid object or reduction in channel width will it refect a significant "wave" backwards.
