Dusting Hole Film Cooling Heat Transfer on a Transonic Turbine Blade Tip
International Journal of Rotating Machinery, Volume 2022, Issue 1, 2022., 2022 Investigated is a transonic turbine blade tip with a squealer rim and a squealer recess, with a single dusting film cooling hole contained within the leading edge region of the squealer recess. Data are provided for transonic flow conditions for a range of film cooling blowing ratios for two tip gap values, using a linear cascade, with no relative ...

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.

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 ...

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.
