The aim of the present chapter is to provide an in‐depth survey of arbitrary Lagrangian–
Eulerian (ALE) methods, including both conceptual aspects of the mixed kinematical …

The geometric conservations laws (GCL) play a fundamental role in computational fluid
dynamics when using moving or even non-moving grids. In this paper, a methodology which …

A comprehensive numerical investigation of incompressible flow about fixed cylinder pairs is
performed. Cylinder arrangements include tandem, side-by-side, and staggered and …

A three‐dimensional Cartesian cut cell method is described for modelling compressible
flows around complex geometries, which may be either static or in relative motion. A …

Trim tabs, small surfaces connected to the end of the craft to control the trim by adjusting the
angle of tab, relative to the larger surface, have been used to optimize the running trim of …

A well-known instability of the high-speed planing crafts is the porpoising instability. This
instability involves periodic, coupled heave/pitch oscillations possibly experienced in a …

A cartesian cut cell method for static body problems was presented in Part A (pp 47-56).
Here, we extend the method to unsteady compressible flows involving arbitrarily moving …

A method is described that allows the simulation of the flow of an incompressible fluid
through rotary displacement pumps. The two-dimensional incompressible Navier–Stokes …

A new methodology is developed to simulate unsteady flows about objects in relative motion
and compute the trajectory of their motion as determined by this flowfield. The method …

In this study, the effects of hydrodynamic interceptors on fast crafts are investigated to find
their optimum geometrical characteristics based on numerical methods. Interceptors are …
