Wave, current and bottom topographical interactions in the coastal ocean bottom boundary layer

A submersible PIV system has been deployed to characterize mean flow and turbulence in the inner part of the coastal ocean bottom boundary layer (BBL), and their interaction with the bottom roughness. Five large datasets, each consisting of ~20,000 velocity distributions, are chosen for analysis to represent flow conditions spanning a range of...

A Hybrid Five-Point Finite Difference Scheme for Convection-Diffusion Equations

In this paper, some five-point finite difference schemes for steady convection-diffusion problems are presented. To begin with, we use the finite volume method (FVM) to discretize the convection-diffusion equation. After that, we present two five-point difference schemes for the approximation of the first order derivatives on faces, one of which...
