RISAssessment of the Reliability of Two-Equation URANS Models in Predicting a Precessing Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A systematic assessment of unsteady Reynolds-averaged Navier–Stokes (URANS) models in predicting the complex flow through a suddenly expanding axisymmetric chamber is reported. Five types of URANS models assessed in the ...

The Topology of a Precessing Flow Within a Suddenly Expanding Axisymmetric Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive study on the flow structure of an ensemble-averaged fluidic precessing jet (FPJ) flow is reported. This study is based on the concepts of critical point theory, previous experimental data, and validated ...
New Understanding of Mode Switching in the Fluidic Precessing Jet Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report the first systematic investigation of the phenomenon of “switching” between the two bistable axial jet (AJ) and precessing jet (PJ) flow modes in the fluidic precessing jet (FPJ) nozzle. While geometric configurations ...
An Improved Algorithm for the Detection of Cirrus Clouds in the Tibetan Plateau Using VIIRS and MODIS Data
Publisher: American Meteorological Society
Abstract: irrus clouds play an important role in the global radiation budget balance. However, the existing MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) cirrus cloud test algorithms struggle to provide accurate cirrus ...
Effect of Gurney Flap on the Aerodynamic Performance of a Flapping Foil: Micro-Aerial Vehicle Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Even with its small size, the Gurney flap (GF) can help considerably in increasing the lift of foils and wings. To exploit this feature, the objective of this research was to numerically study the effects of this flow ...
