摘要: The resistance performance of 49.5m tuna longline fishing vessel is simulated by using CFD software, the simulation results are in good agreements with experimental results, which verified the reliability of numerical calculation. Then change the bulbous bow three parameters of relative extend length, relative depth and maximum width ratio and build the different numerical models, their resistance performance are calculated by CFD method. Comparing and analyzing the calculation results, which show that in considering the general arrangement, driving safety and the strength of bulbous bow, add the bulbous bow extends length, relative depth and maximum width ratio can reduce the total resistance for this type of tuna longline fishing vessel.
