Integration between Measurements and Particle Simulations for Hypersonic Rarefied Flows
The hypersonic rarefied wind tunnel has lately been developed at JAXA. The characteristics of hypersonic rarefied flows have been investigated experimentally and numerically in this work. Using a sphere pendulous model, the test flow has been probed by measuring its displacement due to the aerodynamic force. In addition, a spatial variation of total pressure of the test flow has also been measu...
متن کاملTvd Multigrid Solutions of Three-dimensional Viscous Hypersonic Flows
In the present paper a multigrid technique for three-dimensional perfect gas hypersonic vis-cous ows has been developed, employing a Total Variation Diminishing (TVD) discretization and an upwind correction prolongation, based on a monotonic reconstruction of coarse-grid correction. The methodology has good convergence properties, both for boundary layer ows and complex shock wave-boundary laye...
متن کاملAiaa 2002-3298 Aerodynamics of Two Side-by-side Plates in Hypersonic Rarefied-gas Flows
Hypersonic rarefied-gas flows near two side-byside plates have been studied numerically with the direct simulation Monte-Carlo technique under transitional rarefied-gas-flow conditions (Knudsen numbers from 0.024 to 1.8). Strong influences of the geometrical factor (ratio of distance between plates to plate length) and the Knudsen number on the flow structure (the shape of shock waves, the conf...

Hypersonic rare ed-gas ows near two side-by-side plates have been studied numerically with the direct simulationMonte Carlo technique under transitional rare ed-gas- ow conditions (Knudsen numbers from 0.024 to 1.8). Strong in uences of the geometrical factor (ratio of distance between plates to plate length) and the Knudsen number on the ow structure (the shape of shock waves, the con...
متن کاملAerodynamics of Two Interfering Simple-Shape Bodies in Hypersonic Rarefied-Gas Flows
Hypersonic rarefied-gas flows near two side-by-side plates and cylinders, a plate and cylinder over a plane surface, and a plate behind a cylinder in argon and nitrogen have been studied numerically using the direct simulation Monte-Carlo technique under the transition rarefied-gas-flow regime conditions at Knudsen numbers from 0.004 to 10. Strong influences of the geometrical factor (the ratio...
