A CLSVOF method combined with a block-structured adaptive mesh refinement algorithm is applied to solve the flow field. dan dickerson auburn footballA bow wave is the wave that forms at the bow of a ship when it moves through the water. As the bow wave spreads out, it defines the outer limits of a ship's wake. A large bow wave slows the ship down, is a risk to smaller boats, and in a harbor can damage shore facilities and moored ships. Therefore, ship hulls … See more The size of the bow wave is a function of the speed of the ship, its draft, surface waves, water depth, and the shape of the bow.
