Abstract: In this paper the critical Froude numbers of the wave making system of submarines are evaluated at surface condition.. Focus of this paper is on finding out the hump and hollow of the wave making diagram, and related critical Froude number. Range of maximum Froude number in submarines is extracted statistically. For the study of this phenomenon, three methods are employed; CFD method, Experimental method and Analytical formulas. CFD analysis is performed for a bare hull of a submarine by Flow Vision (V.2.3) software, which is based on the solution of RANS equations. Experiments are conducted in the towing tank of Isfahan University of Technology (IUT) on two models with appendages and different bows (Tango and DREA).
