Effect of shape and sizes of a local heat source on convective heat transfer in a square cavity [PDF]
Компьютерные исследования и моделирование, 2015 Numerical analysis of the effects of the local heat source shape on transient natural convection in a square enclosure has been carried out. The local heat source has rectangular, triangular and trapezoidal shape. The boundary value problem formulated in

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge
Groundwater, EarlyView.A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard

Oscillatory convection and limitations of the Boussinesq approximation [PDF]
Journal of Fluid Mechanics, 2016 We determine the asymptotic conditions under which the Boussinesq approximation is valid for oscillatory convection in a rapidly rotating fluid. In the astrophysically relevant parameter regime of small Prandtl number, we show that the Boussinesq prediction for the onset of convection is valid only under much more restrictive conditions than those that

Scattering Of Internal Waves By Vertical Barrier In A Channel Of Stratified Fluid
International Journal of Applied Mechanics and Engineering, 2015 The problem of two dimensional internal wave scattering by a vertical barrier in the form of a submerged plate, or a thin wall with a gap in an exponentially stratified fluid of uniform finite depth bounded by a rigid plane at the top, is considered in ...

Wind Energy, Volume 29, Issue 10, October 2026.ABSTRACT Sørlige Nordsjø II (SNII) is a planned large‐scale offshore wind farm in the Southern Norwegian North Sea near the Danish border, with phased development targeting a total installed capacity of up to 3 GW. For projects of this scale, site assessments are typically performed using computationally efficient analytical models.

The Liquid Film Flow with Evaporation: Numerical Modelling
MATEC Web of Conferences, 2016 The flow of thin liquid layer on an inclined substrate is investigated numerically. The mathematical modelling is based on the Oberbeck-Boussinesq equations and the generalized conditions on the thermocapillary boundary simplified during the parametrical

Engineering Reports, Volume 8, Issue 9, September 2026.The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

Explicit Solutions of a Gravity-Induced Film Flow along a Convectively Heated Vertical Wall
The Scientific World Journal, 2013 The gravity-driven film flow has been analyzed along a vertical wall subjected to a convective boundary condition. The Boussinesq approximation is applied to simplify the buoyancy term, and similarity transformations are used on the mathematical model of

Adaptive Numerical Modeling of Tsunami Wave Generation and Propagation with FreeFem++
Geosciences, 2020 A simplified nonlinear dispersive Boussinesq system of the Benjamin–Bona–Mahony (BBM)-type, initially derived by Mitsotakis (2009), is employed here in order to model the generation and propagation of surface water waves over variable bottom.

Observed Bottom Intensified Diurnal Currents on the Upper Continental Slope North of Svalbard
Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.Abstract In the Arctic Ocean, dissipation is generally weak except for some hot spots on the continental slope or along the edge of the Yermak Plateau where observations suggest that tidal currents are the main source of dissipation. In this study, we analyze observations collected between September 2017 and November 2019 from a mooring deployed on the
