Numerical and Experimental Validation of a Supersonic Mixing Layer Facility

Applied Sciences, 2022
The design of a supersonic-supersonic mixing layer facility was motivated by the need for a benchmark experimental platform to study the physical phenomena underlying supersonic mixing layers.

Separation Control for a Transonic Convex Corner Flow Using Ramp‐Type Vortex Generators

International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022
A flap can be used to control wing camber and as a high‐lift device. A convex corner is a simplified model of the upper surface of a flap. At transonic speeds, shock‐induced boundary layer separation (SIBLS) occurs at greater freestream Mach numbers and deflection angles. This results in energy losses and a reduction in aerodynamic performance.

Numerical Study of Rectangular Tank with Sloshing Fluid and Simulation of the Model Using a Machine Learning Method

Geofluids, Volume 2022, Issue 1, 2022., 2022
This paper presents a fluid sloshing model using the artificial neural network method (ANN). Determining the fluid sloshing model in the tank is a challenging task due to its nonlinearity and complexity of behavior to its environmental and operational conditions.

Aquatic and riparian ecosystem recovery from debris flows in two western Washington streams, USA

Ecology and Evolution, Volume 10, Issue 6, Page 2749-2777, March 2020., 2020
An exceptionally powerful storm caused large debris flows in two adjacent streams. The two affected streams had been studied prior to the storm providing a rare opportunity to examine ecosystem recovery. We monitored the streams and their riparian zones for 6 years after the disturbances to determine whether recovery rates of biota, physical habitat ...

Design and preliminary experiment of a 0.3 × 0.15 m2 low-disturbance supersonic wind tunnel [PDF]

AIP Advances
To meet the requirement for the low disturbance of wind tunnel flow in supersonic boundary layer transition simulation tests, a low-disturbance supersonic research wind tunnel with a nozzle size of 0.3 × 0.15 m2 and test Mach number of 3.0 was built.

Transitional shockwave/boundary layer interaction experiments in the R2Ch blowdown wind tunnel

Experiments in Fluids, 2022
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

International Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018
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 ...

Susquehanna Shale Hills Critical Zone Observatory: Shale Hills in the Context of Shaver's Creek Watershed

Vadose Zone Journal, Volume 17, Issue 1, Page 1-19, 2018., 2018
Core Ideas Studying the critical zone requires targeted research on water, energy, gas, solutes, and sediments. The SSHCZO targets a 165‐km2 watershed on sedimentary rocks in the northeastern United States. One SSHCZO subcatchment, Shale Hills, provides extraordinary data describing a shale CZ.
