RISDye Visualization of In-Line Twin Synthetic Jets in Crossflows—A Parametric Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a parametric study on the interaction of twin circular synthetic jets (SJs) that are in line with a crossflow over a flat plate. The resulting vortex structures under different actuation, and flow ...
Measuring In-Building Spatial-Temporal Human Distribution through Monocular Image Data Considering Deep Learning–Based Image Depth Estimation
Publisher: ASCE
Abstract: This research estimated the spatial-temporal distribution of humans in buildings through image sensing. Inputs were the in-building network, image sequences recording the movement of human, and camera parameters. Object ...
Improved Spatiotemporal Distributions of Sweeping Jet Film Cooling With a Shaped Exit Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sweeping jet (SJ) is a self-excited flow control device that can generate continuous and periodic flow, which makes it a promising geometry for film cooling. However, the cooling performance of current SJ configurations ...
