A Navier-Stokes processor for biomedical applications

Abstract

VLSI implementation issues in the design of a parallel processor for the solution of a set of Navier-Stokes (NS) equations which model the flow of blood through a stenosis are discussed in this paper. Specifically, the Navier-Stokes equations and the Poisson equation are used for the calculation of the velocities and pressure of the blood in the stenosis. Selection of the stenosis model, definition of the computation grid, selection of the initial conditions and boundary conditions, discretization of the original equations, software simulations with the SIMPLER method are discussed. The impact of these choices on VLSI architecture complexity is investigated.
