Gas Kinetic Scheme Coupled with High-Speed Modifications for Hypersonic Transition Flow Simulations [PDF]

open access: goldEntropy
The issue of hypersonic boundary layer transition prediction is a critical aerodynamic concern that must be addressed during the aerodynamic design process of high-speed vehicles. In this context, we propose an advanced mesoscopic method that couples the

A unified construction of all-speed HLL-type schemes for hypersonic heating computations [PDF]

open access: greenarXiv, 2021
In this paper, a unified framework to develop all-speed HLL-type schemes for hypersonic heating computations is constructed. Such a unified construction method combines two effective improving techniques: a shock robustness improvement and a low-Mach number fix.

Aerodynamic Heating at Hypersonic Speed

open access: hybrid, 2011
At designing and modernization of a reentry space vehicle it is required accurate and reliable data on the flow field, aerodynamic characteristics, heat transfer processes. Taking into account the wide range of flow conditions, realized at hypersonic flight of the vehicle in the atmosphere, it leads to the need to incorporate in employed theoretical ...

A Novel Hypersonic Target Trajectory Estimation Method Based on Long Short-Term Memory and a Multi-Head Attention Mechanism [PDF]

open access: yesEntropy
To address the complex maneuvering characteristics of hypersonic targets in adjacent space, this paper proposes an LSTM trajectory estimation method combined with the attention mechanism and optimizes the model from the information-theoretic perspective.

A Unified Framework for Producing CAI Melting, Wark-Lovering Rims and Bowl-Shaped CAIs [PDF]

open access: yes, 2016
Calcium Aluminium Inclusions (CAIs) formed in the Solar System, some 4,567 million years ago. CAIs are almost always surrounded by Wark-Lovering Rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1 to 100 microns.

Flare-Control Effectiveness at Hypersonic Speeds

open access: bronzeTRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2004
The effects of flare control on the aerodynamic characteristics, performance, and stability of a cylindrical body under laminar and turbulent boundary layer conditions have been studied experimentally and computationally. The experimental study has been carried out in a hypersonic gun tunnel at a Mach number of 8.2 and a Reynolds number of 158,100 ...

Using Electrical Impedance Spectroscopy to Separately Quantify the Effect of Strain on Nanosheet and Junction Resistance in Printed Nanosheet Networks. [PDF]

open access: yesSmall
This article reports on the use of impedance spectroscopy to separate the role of strain on the electrical properties of nanosheets and junctions in MoS2 networks. This is of particular interest as MoS2 nanosheet networks are finding applications in flexible electronics where understanding of the deformation‐induced changes in electrical performance is
