Propeller nominal wake: KVLCC2 -- CFD Online Discussion Forums

November 27, 2017, 14:50	Propeller nominal wake: KVLCC2	#1
Seervan Member Soroush Kargar Join Date: Apr 2017 Posts: 45 Rep Power: 9	Hi all I am trying to asses nominal wake fraction of a ship model: KVLCC2 I have determined the velocity contours at propeller disc. So my question is how to determine nominal wake fraction, w ? The relation is w=1-Va/U which U is the ship or flow velocity. My guess is that I extract the x-velocity values at propeller disc which are the Va values at every cell, then extract them as a XYZ table as .csv, then use the above formula to asses w at every cell, then take an average on them. Is this approach correct? Any ideas? Tnx
