Sawtooth structures are observed in tunneling probabilities with changing Planck's constant
for a periodically perturbed rounded-rectangular potential with a sufficiently wide width for …

Communication blackouts during the atmospheric reentry phase are a significant challenge,
as flight data are lost due to interruptions caused by plasma gas generated by aerodynamic …

In sample-return missions, the reentry velocity of a sample-return capsule is expected to be
approximately 15 km/s; however, the reentry velocity of the Hayabusa sample-return capsule …

The flow enthalpy of an arc-heated wind tunnel is an important parameter for reproducing
planetary entry and performing heating tests. However, its distribution is insufficiently …

A numerical simulation has been performed of a high-velocity argon plasma arc flow in a low
power arcjet including a finite-rate chemical kinetic model. Electrons, ions, molecular ions …

Turbulent plasma flow in large-scale arc heaters such as JAXA 750 kW and NASA 20 MW
facilities was investigated and distributions of flow-field properties were successfully …

A modeling study is conducted to investigate the effect of hydrogen content in propellants on
the plasma flow, heat transfer and energy conversion characteristics of low-power (kW class) …

This work addresses the modeling of high pressure electric discharge in an arc-heated wind
tunnel. The combined numerical solution of Poisson's equation, radiative transfer equations …

An arc-heated wind tunnel is one of the most important facilities to reproduce the high-
temperature environment during atmospheric entry for plasma studies and spacecraft …

Turbulent plasma flows in arc heaters, such as Japan Aerospace Exploration Agency's 750
kW, NASA's 20 MW, and Kyushu University's 20 kW facilities, were investigated, and the …
