Dynamics of Three-Dimensional Shock-Wave/Boundary-Layer Interactions

Datta V. Gaitonde et al.

Summary: Advances in measuring and understanding 2D shock-wave/turbulent-boundary-layer interactions have led to a focus on 3D STBLI, which display greater configuration diversity. Semi-infinite interactions exhibit a conical asymptotic behavior where specifics of the shock-generator become insignificant.

On the accuracy of two-temperature models for hypersonic nonequilibrium flow

Xiaoyong Wang et al.

Summary: Due to the uncertainties in empirical assumptions, the widely-used two-temperature models for hypersonic nonequilibrium flow lack accuracy. To address this, the modified Macheret-Fridman model based on the correction method of the modified Marrone-Treanor model is developed. Several test cases are used to evaluate the accuracy of the modified and widely-used two-temperature models. The study shows that the correction method significantly improves the accuracy of the widely-used two-temperature models and highlights the importance of considering dissociation rates, vibration-dissociation coupling effect, and the non-Boltzmann effect in modeling highly nonequilibrium dissociating flows.

Unsteady behavior and thermochemical non equilibrium effects in hypersonic double-wedge flows

Davide Ninni et al.

Summary: The paper presents highly detailed two-dimensional numerical simulations of hypersonic nitrogen and air flows around a double wedge, focusing on the unsteady behavior and thermo-chemical non-equilibrium effects. The results show that the occurrence of unsteady periodic behavior depends on the flow conditions and is inhibited in the high enthalpy case. Furthermore, discrepancies between the results obtained with different thermo-physical models are observed in the case of high enthalpy flows.

Assessment of Hypersonic Double-Cone Experiments for Validation of Thermochemistry Models

Michael E. Holloway et al.

Summary: The effect of thermochemical kinetics modeling on hypersonic flow over a double-cone geometry is investigated. The results show that the specific thermochemistry model used significantly affects surface properties, especially at high enthalpies. However, the current models fail to reproduce experimental results accurately.

On the influence of non equilibrium in the free stream conditions of high enthalpy oxygen flows around a double-cone

Davide Ninni et al.

Summary: This work presents a detailed analysis of the shock wave/boundary layer interaction in hypersonic flows around a double-cone. Numerical simulations have been carried out to investigate the effects of thermochemical non-equilibrium and surface processes. The study highlights the importance of accurately evaluating the free stream conditions for predicting separation extent and heat transfer in high enthalpy conditions.

Vibrational-Specific Model of Simultaneous N2-N and N2-N2 Relaxation Under Postshock Conditions

Alexander J. Fangman et al.

Summary: This paper discusses the development of an efficient aerothermochemistry model that can be combined with fluid dynamics simulations and maintains the accuracy derived from quantum-mechanical and molecular dynamic principles. Verification tests suggest that this model is accurate and computationally efficient for simulating dissociating nitrogen flows. The inclusion of electronically excited and ionic species may be required for computing relaxation parameters.

Analysis of mass diffusion theory and models for high-temperature multi-component gases

Yuhao Tian et al.

Summary: This study analyzes mass diffusion models for high-temperature multi-component gas flows and finds that the self-consistent effective binary diffusion model and the modified Fick's model perform well in Earth reentry aerothermodynamic simulations. A difference term Ai is proposed to represent the discrepancy between the two models.
