On buoyancy‐driven viscous incompressible flows with various types of boundary conditions
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 103, Issue 11, November 2023., 2023 In this paper, we study the existence and uniqueness of solutions to the initial‐boundary‐value problem for time‐dependent flows of heat‐conducting incompressible fluids through the two‐dimensional channel. The boundary conditions are of two types: the so‐called “do nothing” boundary condition on the outflow and the so‐called Navier boundary conditions

A stochastic stability equation for unsteady turbulence in the stable boundary layer
Quarterly Journal of the Royal Meteorological Society, Volume 149, Issue 755, Page 2125-2145, July 2023 Part B., 2023 The stochastic stability equation for predicting the temporal evolution of the momentum stability correction of turbulent diffusion in a stably stratified boundary layer under the influence of unresolved random processes is validated. Comparison of the probability distribution is calculated from the parametrised model (lower panel) and the data (upper ...

Topology Optimization of Time Dependent Viscous Incompressible Flows
Abstract and Applied Analysis, 2014 In this paper, we consider topology and shape optimization problem related to the nonstationary Navier-Stokes system. The minimization of dissipated energy in the fluid flow domain is discussed. The proposed approach is based on a sensitivity analysis of

MATHEMATICA SCANDINAVICA, 1991 Let \(\Omega\) be a bounded connected open set in \(\mathbb{R}^ n\) with smooth boundary \(\partial\Omega=\Gamma\) and denote by \(\vec u=(u_ 1,\dots,u_ n)\) the unit interior normal vector field defined near \(\Gamma\). Let \(I=(0,b)\), where \(b\in(0,\infty)\), let \(Q=\Omega\times I\), and let \(S=\Gamma\times I\). Denote \(f\mid_ \Gamma=\gamma_ 0 f\
