Available potential energy in Rayleigh-Bénard convection
, 2021 The mechanical energy budget for thermally equilibrated Rayleigh–Bénard convection is developed theoretically, with explicit consideration of the role of available potential energy, this being the form in which all the mechanical energy for the flow is ...

Case Studies in Thermal Engineering, 2023 In order to reveal the combined influences of Rayleigh (Ra) number, Reynolds (Re) number and spanwise aspect ratio (B) on the flow pattern evolution and stability, and heat transfer of Poiseuille-Rayleigh-Bénard (PRB) convection, we presented a set of ...

Numerical analysis of Poiseuille-Rayleigh-Bénard convection in supercritical carbon dioxide
Nuclear Engineering and Technology, 2022 The supercritical carbon dioxide (S–CO2) Brayton cycle is an important energy conversion technology for the fourth generation of nuclear energy. Since the printed circuit heat exchanger (PCHE) used in the S–CO2 Brayton cycle has narrow channels, Rayleigh-

Galerkin method for feedback controlled Rayleigh--Bénard convection [PDF]
, 2004 We employ a Galerkin approximation for the system of equations governing Rayleigh-Bénard convection. This approximation reduces the dimension of the problem by one, while it captures the nonlinear behavior even when only a few basis functions are used ...

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 ...

Hexagonal Cell Formation in Darcy–Bénard Convection with Viscous Dissipation and Form Drag
Fluids, 2017 Recent interest in the effects of viscous dissipation on convective flows in porous media has centred almost exclusively on forced convection flows. In this paper, we investigate the manner in which it affects the onset and early stages of convection in ...

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
