Inverse Design of Axis Fan for Permanent Magnet Drive Motor for Special Vehicles

open access: yesEnergies, 2023
The control of mechanical energy loss is especially key in the design of permanent magnet drive motors for special vehicles. This paper takes a 300 kW high-efficiency motor as an example, and under the operating condition of 9000 rev/min, in order to ...

CFD Analysis of Wind Distribution around Buildings in Low-Density Urban Community

open access: yesMathematics, 2022
The computational fluid dynamics (CFDs) models based on the steady Reynolds-averaged Navier–Stokes equations (RANSs) using the k−ω two-equation turbulence model are considered in order to estimate the wind flow distribution around buildings.

Assessment of Different CFD Modeling and Solving Approaches for a Supersonic Steam Ejector Simulation

open access: yesAtmosphere, 2022
The effects of different modeling and solving approaches on the simulation of a steam ejector have been investigated with the computational fluid dynamics (CFD) technique. The four most frequently used and recommended turbulence models (standard k-ε, RNG

Turbulence models of gravitational clustering [PDF]

open access: yes, 2011
Large-scale structure formation can be modeled as a nonlinear process that transfers energy from the largest scales to successively smaller scales until it is dissipated, in analogy with Kolmogorov's cascade model of incompressible turbulence.
