Efficient Viscous Wave-Resistance Analysis

摘要

The paper reports on approaches to analyse the wave-resistance for viscous, steady-state flows around ships in calm-water conditions. Attention is drawn to the enhancement of the computational efficiency. Emphasis is given to an appropriate initialisation and consideration of the individual time-scales of the transport properties. Examples included refer to the KVLCC2 tanker at Re=4.6 106and Fn=0.142 as well as the Kriso container ship (KCS) at Re=1.4 107 and Fn=0.26. Results indicate a reduction of wall-clock-time by more than one order of magnitude in conjunction with the present approach.
