Adapting a Fourier pseudospectral method to Dirichlet boundary conditions for Rayleigh-Bénard convection [PDF]
Papers in Physics, 2015 We present the adaptation to non-free boundary conditions of a pseudospectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck-Boussinesq equations in a Rayleigh-Bénard cell with no-slip ...

Study of heat and mass transport in Couple-Stress liquid under G-jitter effect
Ain Shams Engineering Journal, 2018 In the present paper, we deal with the effect of G-jitter (time periodic gravity modulation) on the stability of double diffusive convection in couple stress liquid by method of non-linear analysis. The infinitesimal disturbances are expanded in terms of

Sparse nonlinear models of chaotic electroconvection
Royal Society Open Science, 2021 Convection is a fundamental fluid transport phenomenon, where the large-scale motion of a fluid is driven, for example, by a thermal gradient or an electric potential. Modelling convection has given rise to the development of chaos theory and the reduced-

Energy Storage, Volume 8, Issue 4, June 2026.ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.

Localized Convection in Sputnik Planitia, Pluto
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The cellular plains on Sputnik Planitia (SP) are thought to originate from convection in the nitrogen ice layer that fills the basin. Whereas the cells toward the center of SP's cellular plains are wider and interconnected—features explained by vigorous convection—the cells near the margins are smaller and less contiguous, with some appearing ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.
