Numerical studies on modeling the near- and far-field wake vortex of a quadrotor in forward flight
Published 2022“…This article presents the results from flow simulations of quadrotor propellers using the Overset method in ANSYS Fluent 19.2 and the Virtual Blade Model (VBM) method in OpenFOAM as part of ongoing work to establish a wake vortex–based safe separation distance for UAS operations. The near-field flow simulation using the Reynolds-averaged Navier–Stokes turbulence model was validated with mesh convergence and turbulence model studies and verified with simulation and experimental data in the literature to ensure that the propeller simulation methods could generate a realistic near-field flow of multi-rotor UAS in forward flight. …”

A dual-functional benzobisthiadiazole derivative as an effective theranostic agent for near-infrared photoacoustic imaging and photothermal therapy
Published 2016“…Herein, we report a theranostic agent based on a narrow-‐bandgap small molecule, benzo[1,2-c;4,5-c’]bis[1,2,5]thiadiazole-4,7-bis(9,9-dioctyl-9H-fluoren-2-yl)thiophene (denoted as BBT-2FT), with strong absorption of near infrared (NIR) light. Colloidal nanoparticles composed of BBT‐2FT show photoacoustic signal intensity 10 times higher than that of blood, and high photothermal conversion efficiency (η=40%) under irradiation of 800-nm laser light that kills over 90% HeLa cells in 10 mins.…”

Three-dimensional modeling of near-field beam profiles from grating couplers using a deep neural network

In this study, a deep neural network (DNN) modeling technique is developed as a rapid alternative to generate reactive near-field beam profiles of light coupled from SiPh gratings, as compared to the conventional finite-difference time-domain (FDTD) technique. …”
