... thickness of the wall-adjacent layer, (equation), is less than one for all the cases. The time-step is chosen such that the maximum Courant–Friedrichs–Lewy (CFL) number is less than one and the oscillating drag and lift are sampled at a high rate. For a fixed domain size, when the Reynolds number decreases...

... ABSTRACT The estimation of the shape of an AUV and its drag using semi-empirical equations is an important part of its preliminary design. Most of the drag is due to the main body which is often axisymmetric. The drag of axisymmetric bodies can be approximately determined by using Hoerner's...
