Calculation of buoyancydriven 3D cavity flow using a multiprocessor system
Abstract
A multiprocessor system developed for moleculardynamics calculations is applied to threedimensional NavierStokes problems. An algorithm for calculating a buoyancydriven laminar/turbulent flow in a threedimensional cavity is implemented on the processor. Focus is placed on the processor architecture and a database structure required for the implementation of the algorithm. A domaindecomposition technique in which the threedimensional calculation domain is split into a number of slices is selected. A cavity filled with air is considered; its dimensions are 1m x 1m x 0.1m. The solution is obtained on several grids, and it is shown that the solution on the three finest grids deviate very little for the characteristic numbers, with maximum deviation of about 2 pct.
