Submission Instructions:

·       [Identifier] should be [Institute Name]-[Solver Name]. For example, if your institute is Chalmers and solver is SHIPFLOW4.2, identifier should be Chalmers-SHIPFLOW4.2 

Identifier in the Figure should be [Institute Name]/[Solver Name]. For example, if your institute is Chalmers and solver is SHIPFLOW4.2, identifier should be Chalmers/SHIPFLOW4.2 

·      All figures should have aspect ratio of 1:1

·      All figures should be in black and white

·      Authors may change the contour levels for turbulence quantities for better qualitative comparison

                                                                                                      

Remarks:

·         Total wake fraction, where u is the total local velocity, U is the undisturbed velocity (ship speed).

·          is the circumferential angle, counterclockwise from 0° (top position) to 360°; propeller radius R=0.0425m, shaft centerline O is at z/Lpp= -0.04688. The coordinate system is shown as following figure:
