Micro Flow Simulation Using Kinetic and Continuum Approacheslts of the Navier-Stokes equations with the slip boundary condition generally agree with those of the kinetic model Boltzmann equation if the Knudsen number is less than 0.1. A kinetic/continuum hybrid method has also been developed. The hybrid method may be a promising tool for analyzing whole flow regimes from free molecule to continuum flows.作者: HAIL 時(shí)間: 2025-3-23 01:21 作者: 免費(fèi) 時(shí)間: 2025-3-23 08:53
A Hybrid FE/Spectral Analysis of Turbofan Aeroacousticsproach. The most novel feature of the work is the iterative solution technique using a preconditioner based on an axisymmetric geometry and steady flow field. A numerical example illustrates how few Fourier modes need to be retained, and demonstrates the effectiveness of the preconditioner.作者: reptile 時(shí)間: 2025-3-23 13:41
