Thermal convection is an important transport mechanism in many engineering and geophysical flows
We study the effect of the Coriolis force on centrifugal buoyancy-driven convection in a rotating cylindrical shell with inner cold wall and outer hot wall
When Ro−1 = 0 (×, no Coriolis force), Nu is close to the Grossmann & Lohse (2000) theory, as expected
Summary
Thermal convection is an important transport mechanism in many engineering and geophysical flows. Centrifugal buoyancy-driven convection (figure 1) is a canonical thermal convection system to study some of these flows (table 1). The studies with geophysical interests consider this system as a closed dynamical model for the earth’s liquid (outer) core (Busse & Carrigan 1974), or midlatitude atmosphere (Randriamampianina et al 2006; Read et al 2008; Von Larcher et al 2018). The system is a rotating cylindrical shell with inner cold wall and outer hot wall (figure 1). Rotation introduces centrifugal buoyancy (set by centripetal acceleration) and Coriolis forces
