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…

Scale-dependent force balance governs transition to the geostrophic regime in liquid metal rotating convection
Shao-Peng Yang, Lin Sun, Guang-Yu Ding +2
Rotating convection in low-Prandtl-number liquid metal drives dynamo action in the Earth's outer core and is central to planetary interior dynamics. It has been proposed that flow…
