My question has to do with interpreting pressure drop results for turbulent flow in a pipeline static mixer.
Energy dissipation length is a relevant quantity in the design of static mixers, and is defined simply as the length over which energy has been dissipated.
My approach to find that length would be to simulate a typical flow, use slice graphics to visualize the static pressure, and find the length from upstream pressure to zero pressure downstream which occurs right after the flow passes through the mixer.
However, I was also thinking of using the length from upstream pressure to zero pressure after a lengthy recirculation zone.
Anyone have thoughts as to which length to use? I've included an overhead screenshot of a pressure slice in the middle of the pipeline/mixer configuration.
Any advice is appreciated, thanks!
