### Abstract

The feasibility of using this approach to perform transition studies of Marangoni flow in half zone liquid bridges on this computer is examined.

A parallel method for solving the elliptic Navier-Stokes equations for incompressible fluid flows is presented. The parallel implementation strategy is based on grid-partition.

Message-passing protocol MPI has been coded into the code so that it is portable to systems that support this interface for interprocessor communications.

The code is based on a 3D Simplified Marker and Cell primitive variable method applied to a staggered finite-difference grid.

A parallel multisplitting kernel is introduced for the solution of the pseudo-pressure elliptic equation which represents the most time-consuming part of the algorithm.

Numerical experiments and parallel performance measurements are made on the implemented code to check the numerical properties and parallel efficiency.
