    Research on Temperature Distribution of Large Permanent Magnet Synchronous Direct Drive Wind Turbine by Zhengjun Huang, Quan Liu, Yuxin Hao

    Published 2023-05-01
    “…In this paper, an electromagnetic analysis model is established by using the parameters of a 4 MW wind turbine; the losses of each part of the generator under rated load and three-phase short-circuit conditions are calculated, respectively; and the heat source is imported into the workbench fluent software to determine the cooling mode, so as to obtain the magnetic-thermal-flow field coupling model of permanent magnet synchronous direct drive wind turbine. …”

    Identifying extra high frequency gravitational waves generated from oscillons with cuspy potentials using deep neural networks by Li-Li Wang, Jin Li, Nan Yang, Xin Li

    Published 2019-01-01
    “…During oscillations of cosmology inflation around the minimum of a cuspy potential after inflation, the existence of extra high frequency gravitational waves (HFGWs) (∼GHz) has been proven effectively recently. Based on the electromagnetic resonance system for detecting such extra HFGWs, we adopt a new data processing scheme to identify the corresponding GW signal, which is the transverse perturbative photon fluxes (PPF). …”

    Effect of Dissolved Salts on Steady-State Heat Transfer Using Excessive Cooling by Water-Air Mists by Constantin Alberto Hernández-Bocanegra, Francisco Andrés Acosta-González, José Ángel Ramos-Banderas, Nancy Margarita López-Granados

    Published 2022-05-01
    “…The experimental system is based on a calorimeter that measures heat flux removed by water-air mist sprays from 8 mm diameter × 2.5 mm thickness platinum samples heated by electromagnetic induction. During steady-state experiments, a solid-state controller equilibrates automatically the rate of heat generation with the rate of heat removal to reach a constant temperature. …”
