Vortex structure and small scale characteristics in turbulent Rayleigh–Bénard convection with mixed isothermal–adiabatic bottom boundary

open access: yesAIP Advances, 2023
Turbulent Rayleigh–Bénard convection with a mixed isothermal–adiabatic bottom boundary is simulated to investigate the effect of a nonideal thermal boundary on vortex structure and small-scale characteristics in turbulent convection.

Exact Null Controllability of a One-Dimensional Wave Equation with a Mixed Boundary

open access: yesMathematics, 2023
In this paper, exact null controllability of one-dimensional wave equations in non-cylindrical domains was discussed. It is different from past papers, as we consider boundary conditions for more complex cases.

Effective surface and boundary conditions for heterogeneous surfaces with mixed boundary conditions [PDF]

open access: yesJournal of Computational Physics, 2016
To deal with multi-scale problems involving transport from a heterogeneous and rough surface characterized by a mixed boundary condition, an effective surface theory is developed, which replaces the original surface by a homogeneous and smooth surface with specific boundary conditions. A typical example corresponds to a laminar flow over a soluble salt

Mixed-lubrication analysis of misaligned journal bearing considering turbulence and cavitation

open access: yesAIP Advances, 2022
By integrating the average flow equation and Ng–Pan turbulence model using the boundary condition of mass conserving [Jakobsson-Floberg-Olsson (JFO)], a mixed lubrication model for misaligned bearing was established considering the effects of turbulence ...

On a nonlocal problem for impulsive differential equations with mixed maxima

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2022
A nonlocal boundary value problem for a first order system of ordinary integro-differential equations with impulsive effects and mixed maxima is investigated. The boundary value problem is given by the integral condition.

Mixed boundary conditions in Euclidean quantum gravity [PDF]

open access: yesClassical and Quantum Gravity, 1995
This paper studies a new set of mixed boundary conditions in Euclidean quantum gravity. These involve, in particular, Robin boundary conditions on the perturbed 3-metric and hence lead, by gauge invariance, to Robin conditions on the whole ghost 1-form.
