Resistance & Propulsion
Speed-power, propeller design, planing hulls, wake and CFD.
What this expert provides
The Resistance & Propulsion expert predicts the power a ship needs and designs the propeller that delivers it: calm-water resistance, the speed-power curve with the propeller curve for engine matching, B-series propeller selection with cavitation checks, planing hull resistance, wake field analysis, hull dimension optimisation, and the set-up and verification of CFD and model tests.
Expert Profile
Uses Holtrop-Mennen for displacement ships and Savitsky for planing hulls, the Wageningen B-series for the optimum diameter or rate of rotation with Keller and Burrill, and ITTC procedures for CFD verification (GCI) and model-test extrapolation. Model tests, CFD and sea trials you supply take precedence over the regressions. Gives the delivered power and rpm to the marine engineering expert.
