Frequency-domain and spectral-domain models use the frequency-dependent hydrodynamic coefficients directly in their equations of motion, as described in detail in Chapters 2 and 4, respectively. The key difference between a WEC array model and a single WEC model is the number of degrees-of-freedom (or modes) for which the system needs to be solved.

Generally, two challenges exist for simulating the liquid-particle flow: (1) accurately calculating the hydrodynamic interactions (i.e., hydrodynamic force and torque); and (2) tracking the position of the particle. For a complicated geometry, it is extremely difficult to.

The main intention of this article is to examine the heat transmission of the flow of Eyring–Powell fluid over an unstable oscillatory porous stretching surface. The effect of thermal radiation on the fluid flow is investigated, where the flow is actuated by the unbounded flexible surface which is extended occasionally to and fro on its plane.

approach was then to approximate a hydrodynamic flow by a large number of constant states, compute their interactions exactly, and average the results in a conservative fashion. This procedure leads to an accurate and very well-behaved treatment of shock discontinuities.
