Numerical studies on modeling the near- and far-field wake vortex of a quadrotor in forward flight by Nathanael, Joshua Christian, Wang, John Chung-Hung, Low, Kin Huat

“…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. …”

What Do We Mean When We Write About Ethics, Equity, and Justice in Engineering Design? by Das, Madhurima, Roeder, Gillian, Ostrowski, Anastasia K, Yang, Maria C, Verma, Aditi

“…We conduct a review of three leading scholarly engineering design venues to investigate how, when, and why these terms — “ethics,” “equity,” and “justice,” and variations — appear in the engineering design literature and what scholars mean when they use them. …”

Is self-explanation better than explaining to a fictitious student when learning from video lectures? by Pi, Zhongling, Zhang, Yi, Shi, Dongyuan, Guo, Xin, Yang, Jiumin

“…Students in the conditions that included both self-explanations and instructional explanations demonstrated a higher level of organization and elaboration than those in the instructional explanation condition. When compared to the self-explanations condition, additional instructional explanations had no effect on learning performance or internal attention. …”
