We investigate, for linear and higher-order elements, various ways of calculating the advective limit of the stabilization parameter (“ τ ”) used in the streamline-upwind/Petrov–Galerkin (SUPG) formulation of flow problems. In the context of a

For the streamline-upwind/Petrov-Galerkin and pressure-stabilizing/Petrov-Galerkin formulations for flow problems, we present in this paper a comparative study of the stabilization parameters defined in different ways. The stabilization parameters ar

A comparative investigation, based on a series of numerical tests, of two purely explicit and one semi-implicit finite element methods used for incompressible flow computation is presented. The ‘segregated’ approach is followed and the equations

This paper reports on the development of a semi-implicit projection-type scheme for solving incompressible Navier-Stokes and energy equations. The numerical scheme employs a finite-element method using a time-splitting method to integrate the two-dim

Abstract The use in drill bits of individual asymmetric nozzles, with special interior transitional surfaces, significantly improves the rate of penetration (ROP) compared to that achieved with conventional circular nozzles. The new fluted nozzles ch

The development of a nozzle to produce regions of negative pressure when impinging upon a standoff surface has been a goal of researchers for several decades. A series of such nozzles has been recently developed by the authors. In this work we will r
