Incompressible Navier-Stokes Computations in Aerospace Applications and Beyond

摘要

Recent progress in developing computational procedures for viscous incompressible flow is presented. Two different flow solvers are examined, one using an artificial compressibility method and the other using a pressure projection method, followed by applications to problems of engineering interest. Computed examples include pulsitile flow in a constricted channel, wing tip vortex formation and propagation, advanced impeller analysis for liquid rocket engine, and the development of a ventricular assist device. The last example serves as an extension of this computational technology to a non-aerospace application. Numerical issues dealing with these applications are discussed both from the algorithm development and from application point of view.
