In this paper, we used computational fluid dynamics simulation (ANSYS CFX) to compare the performance of surfboard fins with grooves (and a bumpy-leading edge) to conventional surfboard fins. The simulations predicted the performance of each type of

The time-averaged film thickness of the coating on a smooth strip from a bath can be predicted by the Landau-Levich (LL), and Derjaguin theory for low inertia and low Capillary number, Ca. Using the smoothed particle hydrodynamics (SPH) method incorp
