Effect of trim on container ship resistance at different ship speeds and drafts
TL;DR: The resistance of a container ship at three different Froude numbers and drafts is predicted using RaNS simulations, demonstrating that the optimum trim angle varies with ship speed and draft.

Solution of the implicitly discretised reacting flow equations by operator-splitting
TL;DR: In this article, a non-iterative method for handling the coupling of the implicitly discretised time-dependent fluid flow equations is described, based on the use of pressure and velocity as dependent variables and is hence applicable to both the compressible and incompressible versions of the transport equations.
