Hi all
im working on simulating flow through an end-suction impeller with its volute , i have defined the inlet boundary condition as inlet volume flow of 0.0466 m3/sec , and outlet boundary condition as environmental pressure , however, the results are totally in-correct..
i have used internal anaylsis , with global rotating system of 185 rad/sec. and since im new in using flow simulation , i think i have must missed some parameter that missed-up my simulation , i apprecite your help in case you have went through such case?
is the flow entering radially?
how far are your bcs from your rotating region?
what are you comparing the results to?
if you're new to using rotation i would recommend that you go through the technical reference, solving engineering problems documents and also the kb to make sure you have followed all the recommendations for rotating regions.
the software has been validated so most commonly, problems come from setups that don't match or being outside the limitations of the software
