Abstract:
In a multiblock system for iteratively processing the pseudocompressibility equations as a prediction of steady, incompressible fluid flow over a given geometry, a method of coupling solutions to the pseudocompressibility equations between blocks of the multiblock system comprising the steps of:creating an overlapping multiblock grid model of the given geometry, each block being defined by boundary nodes and containing interior nodes wherein boundary nodes from one block overlap to interior nodes of an adjoining block;updating, at each iteration, boundary nodes from the one block overlapping to interior nodes of the adjoining block, wherein updated boundary nodes for the one block are equal to a difference between corresponding boundary nodes for the one block and overlapped interior nodes of the adjoining block; andprocessing, utilizing the pseudocompressibility equations, both boundary and interior nodes of each block according to a central finite differencing method wherein equation solutions at updated boundary nodes of the one block overlapping to interior nodes of the adjoining block use boundary and interior nodes of the adjoining block, whereby the equation solutions at updated boundary nodes are coupled between the one block and the adjoining block.
