Numerical study of particle dynamics in a falling-ball viscometer
… viscometer. Through a study of a classical 2-D cavity problem, the cause of the instability requiring the restricted time step is identified. For this cavity problem, a modification of the usual treatment of the boundary condition for the stream function relaxes the restriction on the time step. …

A Complex-Envelope FDTD Formulation Using Real-Valued Field-Variables
… matrices. Results are presented for a 2D cavity problem with an electric current source. A reference solution for this problem is obtained by first solving the problem in the frequency domain and then transform it to the time-domain using the inverse fast Fourier transform (IFFT). …

Gravity-driven continuous thin film flow over topography
… of inertia being of particular interest. The problem is solved using a hierarchy of models based, in order of decreasing complexity, on (i) the full Navier-Stokes system of equations; (ii) a depth averaged form of the latter; (iii) the lubrication equations. Every effort has been made to solve …

The simulation of fluid flow processes using vector processors
… nature of the equations. The first two problems are isothermal flows, viz, the 'moving lid cavity' and the 'sudden expansion in a duct' problem. A study of where the greatest computational effort is expended, and subsequent vectorisation leads to 98% of SIMPLE being modified. This …

A Fourier Solution for Electromagnetic Scattering by a Covered Rectangular Cavity
… scattering from a two-dimensional rectangular cavity embedded in an infinite metallic surface that has been covered with a dielectric material. The transverse magnetic and transverse electric polarizations are both considered. The rectangular geometry of the embedded cavity allows for the use …

Computations of fully nonlinear three-dimensional wave-body interactions
… in hydrodynamics of wave-body interaction problems become critically important when large-amplitude body motions and/or extreme surface waves are involved. Accurate prediction and understanding of these fully nonlinear effects are still challenges in the design of surface ships and marine …

Computations of bubble dynamics with heat transfer
… a numerical tool to simulate multi-fluid flow problems and assess its suitability to study the enhancement effect of an ellipsoidal air bubble on heat transfer from a heated flat plate immersed in water, and the resulting flow patterns. The Volume-of-Fluid (VOF) method is adopted to model the …
