    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

    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 review of feature extraction methods in vibration-based condition monitoring and its application for degradation trend estimation of low-speed slew bearing by Caesarendra, Wahyu, Tjahjowidodo, Tegoeh

    Published 2018
    “…This paper presents an empirical study of feature extraction methods for the application of low-speed slew bearing condition monitoring. The aim of the study is to find the proper features that represent the degradation condition of slew bearing rotating at very low speed (≈ 1 r/min) with naturally defect. …”
