The students of the department of maritime technology should have a proper understanding of hydrodynamicphenomena, including hull wave phenomena, because ships are advanced on the principle of hydrodynamics and greatlyinfluenced with hull wave phenomena. It is, however, not easy for the students to understand the phenomena withoutproper learning aids.We have been trying to make learning aid used in class like flow visualization materials in order to help thestudents understand hydrodynamic phenomena around ships, and have already developed flow visualization materials ofthe propeller thrust and the rudder force. And this time we worked on the visualization of hull wave phenomena, causinghull wave phenomena by the computational fluid dynamics software. It was based on the experiment in the water tank,making use of a sphere in place of a real ship.This paper presents how we tried and succeeded in visualizing hull wave phenomena.
