Abstract

In this paper, we develop an implicit coupled density based solver called coupledFoam in the framework of OpenFOAM. The solver uses the Steger-Warming flux vector splitting to achieve an implicit discretization. BoomerAMG precondition and GMRES iterative method are applied to solve the coupled equation. Data structure has been designed to store the coupled matrix. To support the linear solver in Hypre, data interface is designed. The details of the implementation are presented in this paper. The steady-state oblique shock test case and unsteady-state forward step test case are tested. The flow field characteristics of coupledFoam are smoother than that of rhoCentralFoam.

Prediction and visualization of supersonic nozzle flows using OpenFOAM
Abstract
At low altitudes during rocket flight, the atmospheric pressure is higher compared to the design pressure of the nozzle at the exit. This leads to the formation of overexpansion shock, and consequently, flow separation. When the separation is ...
Numerical flow visualization of a single large-sized bubble in turbulent Couette flow using OpenFOAM
Abstract
Owing to different flow conditions—for example, Poiseuille and Couette flow—one could expect different deformations of large-sized bubbles; however, bubble dynamics has been mostly investigated in channel flow. Consequently, an intermediate flow ...
