Waterjet Propulsion and Thrust Deduction
Artikel i vetenskaplig tidskrift, 2014

The goal of this article is to describe and investigate the parameters that play a role in the waterjet–hull interaction. In general, these parameters can be split into sinkage, trim, and local flow variation from the bare hull to the self-propelled hull. Each of these parameters has in turn been split into components, which are estimated in relative size. For this purpose, a newly developed method for modeling waterjet-driven ves- sels is used. Knowing the magnitude of each single parameter separately helps to understand the physics behind the thrust deduction and may aid in the optimization of the hull/propulsor configuration.
