Linearized Richtmyer-Meshkov flow analysis for impulsively accelerated incompressible solids.

We present an analytical study of the linearized impulsive Richtmyer-Meshkov flow for incompressible elastic solids. Seminumerical prior investigations of a related shock-driven compressible elastic problem suggest that the interface amplitude remains bounded in time, in contrast to the unstable behavior found for gases. Our approach considers a base unperturbed flow and a linearization of the ...

Analysis of Incompressible fluid flow over wedge with different angles

The title of our research paper is “Analysis of Incompressible fluid flow over wedge with different angles”. The basic objective of this research work is to optimize the fluid flow over different wedges and it angles. The optimization is done by varying wedge angle, its parameters considering fluid flow parameters also. The analysis of wedge is carried out in both 3D and 2D from which various r...

Eigenvalue analysis of the SIMPLE preconditioning for incompressible flow

In this paper, an eigenvalue analysis of the SIMPLE preconditioning for incompressible ow is presented. Some formulations have been set up to characterize the spectrum of the preconditioned matrix. This leads to a generalized eigenvalue problem. The generalized eigenvalue problem is investigated. Some eigenvalue bounds and the estimation for the spectral condition number in the symmetric case a...

General Methodologies for Incompressible Flow Design Problems

Two design methodologies based on Incomplete-Gradient adjoint approaches for ow problems governed by the incompressible Navier-Stokes (NS) equations are presented. The main features of the algorithms is that they avoid solving the adjoint equations, saving an important amount of CPU time. Furthermore, the methodologies are general in the sense that they do not depend on the geometry representat...
