SPOT: Point Cloud Based Stereo Visual Place Recognition for Similar and Opposing Viewpoints
Spencer Carmichael, Rahul Agrawal, Ram Vasudevan +1
Recognizing places from an opposing viewpoint during a return trip is a common experience for human drivers. However, the analogous robotics capability, visual place recognition (V…
Direct numerical simulation benchmarks for the prediction of boundary layer bypass transition in the narrow sense
Xiaohua Wu, Carlos A. Gonzalez, Rahul Agrawal
We report a comprehensive set of direct numerical simulation benchmarks of bypass transition in the narrow sense with inlet freestream turbulent intensity levels of 0.75%, 1.5%, 2.…
Development of transitional Reynolds number correlation and assessment of RANS for predictions of bypass transition
Carlos A. Gonzalez, Rahul Agrawal, Xiaohua Wu
We present direct numerical simulations (DNSs) of bypass transition over a flat plate with inlet freestream turbulence intensity levels of 0.75%, 1.5%, 2.25%, 3.0%, and 6.0%, respe…
Large eddy simulation of ocean mesoscale eddies
Pavel Perezhogin, Arun Balakrishna, Rahul Agrawal
Mesoscale eddies produce lateral (2D) fluxes that need to be parameterized in eddy-permitting (1/4-degree) global ocean models due to insufficient horizontal resolution. Here, we s…
