CALCULATION OF NON-ISOTHERMAL MOTION OF A TWO-PHASE COMPRESSIBLE MEDIUM AT IMPLOUSION
Известия высших учебных заведений: Проблемы энергетики, 2018 Hydrodynamic processes in a vertical well casing during implosion are considered. Mathematical modeling of the motion of a two-phase medium with a free surface is based on the volume of fluid method. Unsteady Reynolds-Averaged Navier-Stokes equations are

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study
Quarterly Journal of the Royal Meteorological Society, EarlyView.Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

Estimates for the two-dimensional Navier-Stokes equations in terms of the Reynolds number [PDF]
, 2006 The tradition in Navier-Stokes analysis of finding estimates in terms of the Grashof number $\bG$, whose character depends on the ratio of the forcing to the viscosity $\nu$, means that it is difficult to make comparisons with other results expressed in ...

Modeling and simulation of air pollutant distribution in street canyon area with Skytrain stations
Advances in Difference Equations, 2019 This paper focuses on effects of the wind flow velocity on the air flow and the air pollution dispersion in a street canyon with Skytrain. The governing equations of air pollutants and air flow in this study area are the convection–diffusion equations of

Turbulence modeling for hypersonic flows [PDF]
Turbulence modeling for high speed compressible flows is described and discussed. Starting with the compressible Navier-Stokes equations, methods of statistical averaging are described by means of which the Reynolds-averaged Navier-Stokes equations are ...
