Turbomachinery flow fields have been simulated through the use of computational techniques for approximately two decades.

Advances in computing hardware and the use of parallel algorithms have. Publisher Summary. The perspectives of the use of parallel computers for computational fluid dynamics (CFD) are analyzed in this chapter through the application of some CFD codes for the solution of typical problems on different scalable distributed-memory multicomputers such as INTEL IPSC/, IBM, and HP (CONVEX Metaseries).

This chapter continues the presentation of a new parallel computational fluid dynamics (CFD) algorithm on unstructured grids.

The chapter demonstrates the code's ability to solve the 3-D Navier-Stokes equations. The 2-D and 3-D results presented show excellent performance both.

Computational fluid dynamics (CFD) plays an essential role to analyze fluid flows and heat transfer situations by using numerical methods.

Turbomachines involve internal and external fluid flow problems in compressors and turbines. CFD at present is one of the most important tools to design and analyze all types of turbomachinery. The main purpose of this paper is to review the state of the.

Traditionally, airfoils have been designed by stacking 2-D sections to create a 3-D model. While 3-D analysis has become common, 3-D design has not. Today, pseudo 3-D design is accomplished by adjusting 2-D parameters in response to 3-D analysis.

This approach benefits from a large experience base in 2-D design and a good understanding of the 2-D. () Development of a parallel computational fluid dynamics algorithm on a hypercube computer.

The application of 3D computational fluid dynamics Three-dimensional computational fluid dynamics (CFD) started to be developed in the s and early s. The first methods were inviscid and ran on very coarse meshes of only a few thousand points per blade passage.

These methods were generally based on the Euler blade-to-blade approach, described in Chapter. Abstract. In this paper we give an overview of the parallelization of the 3-D CFD package N3S for complex industrial incompressible flow simulation on parallel distributed memory platforms using the message passing paradigm.
