Transitional shockwave/boundary layer interaction experiments in the R2Ch blowdown wind tunnel
Transitional Shockwave/Boundary Layer Interactions (SBLI) is studied experimentally. Experiments are conducted on a hollow-cylinder flare model in the R2Ch blowdown facility at a Mach number of 5 for three different Reynolds numbers in the transitional regime.

Research Progresses of Flash Evaporation in Aerospace Applications
Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low‐pressure environment and flash evaporation have unique characteristics and superiority in high altitude and outer space ...

Atomic Layer Deposition in Transistors and Monolithic 3D Integration
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Wind Tunnel Testing on Start/Unstart Characteristics of Finite Supersonic Biplane Wing
This study describes the start/unstart characteristics of a finite and rectangular supersonic biplane wing. Two wing models were tested in wind tunnels with aspect ratios of 0.75 (model A) and 2.5 (model B). The models were composed of a Busemann biplane section.

Control of Reynolds number in a high speed wind tunnel [PDF]
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel test data was made to design the ...

Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert
What are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of

Infra‐Through Ultrasonic Piezoelectric Acoustic Vector Sensor Particle Rejection System
Sensor elements which employ fine filaments are often vulnerable to particulate fouling when used in certain operational field conditions. Depending on the size, attraction level, thermal and electrical conduction, and charge accumulation properties of the particles, erroneous readings can be easily generated in such “dirty” environments.
