We compare high-order methods including spectral difference (SD), flux reconstruction (FR), the entropy-stable discontinuous Galerkin element method (ES-DGSEM), modal methods, and WENO to select best candidate simulate strong shock waves characteristic of hypersonic flows. consider several benchmarks, Leblanc modified shock-density wave interaction problems that require robust stabilization pos...

A review of the state-of-the-art in hypersonic aeroelasticity and aerothermoelasticity is provided. Recently, the main focus in this area has been on the development of computational aeroelastic and aerothermoelastic methods capable of studying complete hypersonic vehicles. Thus, in addition to a survey of studies conducted in this area over the past six decades, two important issues are a focu...

A hybrid particle-continuum computational framework is developed and presented for simulating hypersonic interacting flows, aimed to be faster and more accurate than conventional numerical methods. The framework consists of the direct simulation Monte Carlo-Information Preservation (DSMC-IP) method coupled with a Navier-Stokes solver. Since the DSMCIP method provides the macroscopic information...

While flamelet-based progress variable models have matured to production-level in recent years for incompressible flows, little development toward compressible formulations of the flamelet model has ensued. For supersonic and hypersonic flows exhibiting combustion, an applicable flamelet-based combustion model must reflect the compressible nature of the flow, the tight coupling of the flow and ...

The intent of this study is to evaluate existing gaps in computational fluid dynamics (CFD) technology with an emphasis on hypersonic flow modeling. The importance of validation is highlighted, especially with respect to the dearth of available hypersonic flow data. Modeling challenges relevant to hypersonic air-breathing propulsion, such as multi-phase flow and turbulent mixing, are discussed ...

The hypersonic effect is a phenomenon in which sounds containing significant quantities of non-stationary high-frequency components (HFCs) above the human audible range (max. 20 kHz) activate the midbrain and diencephalon and evoke various physiological, psychological and behavioral responses. Yet important issues remain unverified, especially the relationship existing between the frequency of ...
