Two-Dimensional Lattice Boltzmann for Reactive Rayleigh–Bénard and Bénard–Poiseuille Regimes
Entropy, 2015 We perform a computer simulation of the reaction-diffusion and convection that takes place in Rayleigh–Bénard and Bénard–Poiseuille regimes. The lattice Boltzmann equation (LBE) is used along with the Boussinesq approximation to solve the non-linear ...

Numerical Study of Rotating Thermal Convection on a Hemisphere
Fluids, 2020 Numerical simulations of rotating two-dimensional turbulent thermal convection on a hemisphere are presented in this paper. Previous experiments on a half soap bubble located on a heated plate have been used for studying thermal convection as well as the

A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection
Advanced Functional Materials, Volume 36, Issue 2, 5 January 2026.A non‐contact light‐induced droplet manipulation strategy fueled by mid‐infrared (MIR) light irradiation is introduced. No additional additives and/or complex substrate are required. Here, thermocapillary convection, directly generated by temperature gradient at outer surface of droplet via localized surface heating, plays a key role to propel the ...

Advanced Science, Volume 13, Issue 5, 27 January 2026.We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Biotechnology Journal, Volume 21, Issue 1, January 2026.Graphical Abstract and Lay Summary Platelets (PLTs) are small blood cells that play a vital role in stopping bleeding. After donation, they are stored in special bags, but their quality decreases over time. One reason for this decline is the mechanical stress they experience during collection, processing, and storage.

Transitions between turbulent states in rotating Rayleigh-Bénard convection [PDF]
, 2009 Weakly rotating turbulent Rayleigh-Bénard convection was studied experimentally and numerically. With increasing rotation and large enough Rayleigh number a supercritical bifurcation from a turbulent state with nearly rotation-independent heat transport ...

Case Studies in Thermal EngineeringIn order to understand heat transfer characteristics and obtain a heat transfer correlation of Poiseuille-Rayleigh-Bénard (P-R-B) convection in the thermal entrance region of a horizontal rectangular channel, we performed a series of the direct numerical
