A three-stage Runge-Kutta (RK) scheme with multigrid and an implicit preconditioner has been shown to be an effective solver for the fluid dynamic equations. Using the algebraic turbulence model of Baldwin and Lomax, this scheme has been used to solv

We have used an acousto-optic modulator (AOM) to impose a frequency-modulated signal on an incident laser beam. The incident laser beam is focussed into the AOM where it undergoes Bragg diffraction and is then retro-reflected. The diffracted beam is

Several schemes for introducing an artificial dissipation into a central difference approximation to the Euler and Navier?Stokes equations are considered. The focus of the paper is on the convective upwind and split pressure (CUSP) scheme, which is d

During offshore lifting operations, appropriate characterization of the dynamic forces is critical to ensuring that the proper lifting equipment has been selected and designed. When a load is supported by a wire rope, or any member that will not supp

Abstract The paper is concerned with the numerical simulation of fluid-structure interaction (FSI) of a pipeline span exposed to sea bottom currents. The pipeline lies on the seabed at one end and departs the seabed to attach to a PLET (pipeline end

Today, it is a standard technique to accelerate the convergence of explicit multistage time-stepping schemes to steady state using implicit residual smoothing (IRS) together with multigrid. In the past, various IRS methods have been developed. They a

We have used an acousto-optic modulator (AOM) to impose an amplitude-modulation signal on an incident laser beam. The amplitude-modulated beam is retroreflected through the AOM. This beam is diffracted again by the AOM so that it overlaps the inciden

We demonstrate that an electro-optic phase modulator (EOM) can be used as a constituent of a corner-cube-based modulated high-speed retro-reflector. We performed experiments to investigate the efficiency of the phase modulation produced by an EOM as

Publisher Summary This chapter presents a fast multigrid solver for the steady incompressible Navier–Stokes equations. With this approach, the spatial discretization correctly distinguishes between the advection and elliptic parts of the operator,
