Abstract: Finite-difference techniques based on boundary-fitted coordinates have been developed to study the flow of a stably stratified viscous fluid past a circular cylinder. A time-dependent approach is ...

Abstract: A numerical study has been conducted to investigate the behavior of the vortical wake created by a square cylinder placed in a laminar boundary-layer flow. The calculations are performed by ...

Abstract: In this study, an investigation using a three-dimensional numerical model, which treats conservation of mass, momentum, and salinity simultaneously, was carried out to study the character of a ...

Abstract: We conducted a flow simulation to study the laminar flow in a three-dimensional rectangular cavity. The ratio of cavity depth to width is 1:1, and the span to width aspect ratio (SAR) is ...

Abstract: This study accurately predicts cases of turbulent flow around a surface-mounted two-dimensional rib of varying length. The numerical method employs a finite-difference scheme for integrating the elliptic Reynolds-averaged ...

Abstract: The purpose of the present study is to develop a numerical model for the investigation of water waves propagating over a pair of impermeable submerged obstacles. The mathematic model is formulated by coupling solutions of ...

Abstract: A numerical technique for integrating the fully elliptic Reynolds-averaged Navier-Stokes and diffusion equations has been used to investigate the effect of ambient density stratification on the flow characteristics of a ...
