An experimental study on the heat transport in porous media convection
Jing Dong, Lu Zhang, Ke-Qing Xia
We investigate the heat transport in porous media convection over a wide Rayleigh--Darcy number range of , and a Darcy number range of $6.18\times1…

Multiple critical Froude numbers for the centrifugal effects on heat transport in rotating Rayleigh-Bénard convection
Zhi-Cong Kang, Guang-Yu Ding, Lu Zhang +1
The influence of centrifugal effects in rotating Rayleigh-Benard convection is investigated using direct numerical simulations. We find that the Nusselt number decreases beyond a c…

Subcritical transition to turbulence in buoyancy-driven flows with multiple hysteresis loops under quasi-one-dimensional confinement
Lu Zhang, Ke-Qing Xia
We present both static and quasi-static direct numerical simulations of Rayleigh-Bénard convection in a quasi-one-dimensional domain, revealing for the first time a clear subcriti…
