Hypersonic heating computations are still challenging due to difficulties in “(A) robust
capturing of shockwaves” and “(B) accurate prediction of heating”. Based on our numerical …

The reduced dissipation approach is applied to AUSM-family flux functions of SLAU2 (as
well as its predecessor, SLAU) and AUSM+-up for high resolution simulations. In this …

Roles of flux functions (such as SLAU2 Kitamura and Shima, 2013), limiters, and
reconstructed variables are thoroughly investigated in problems related to hypersonic …

For most re-entry capsules, the shape of the forebody of the capsule is designed based on
the blunted nose cone. A similar shape can be created using a hyperboloid of revolution that …

Abstract An AUSM (Advection-Upstream-Splitting-Method) family flux function SLAU (Simple
Low-dissipation AUSM) 2, developed by Kitamura, K., and Shima, E.[J. Comput. Phys. 245 …

Space transportation vehicles have asymmetric protuberant devices on their surfaces, such
as cable ducts. Such protuberances, typically arranged asymmetrically with respect to the …

A simple and efficient a posteriori slope limiter (“Post Limiter”) is proposed for compressible
Navier–Stokes and Euler equations, and examined in 1D and 2D. The Post Limiter tries to …

A slender-bodied vehicle with asymmetrically arranged protuberance generates strong side
force due to asymmetric vortices, even at a low angle-of-attack. We investigated effects of the …

The presence of protuberances can create an asymmetric flowfield, which contributes to side
forces in slender-bodied launch vehicles. In this study, we conduct numerical calculations …
