A Non-Hydrostatic Depth-Averaged Model for Hydraulically Steep Free-Surface Flows

Fluids, 2017
This study describes the results of a numerical investigation aimed at developing and validating a non-hydrostatic depth-averaged model for flow problems where the horizontal length scales close to flow depth.

Convective layered flows of a vertically whirling viscous incompressible fluid. Velocity field investigation

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
This article discusses the solvability of an overdetermined system of heat convection equations in the Boussinesq approximation. The Oberbeck-Boussinesq system of equations, supplemented by an incompressibility equation, is overdetermined.

Glazing Effects on Dynamic‐Insulation TSC Façades: A CFD‐Supported Experimental Study of Flow, Heat Transfer, and Ventilation Preheating

Energy Science &Engineering, EarlyView.
Glazed transpired solar collectors achieve 48–75% efficiency and 11% more seasonal heat than unglazed designs by cutting convective losses, while both offer complementary benefits for ventilation preheating and dynamic wall insulation, with paybacks of 5.5–6.8 years.

Propagation of internal gravity waves: Optimal vertical discretisation and grid design based on numerical error analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.
