Heat transport and flow structures in inclined circular enclosures

Long-term seasonal weather variations can arise from a misalignment between sunlight and the direction of a planet's gravitational pull, though plausible reasons are yet unclear. Inspired by such events, we have carried out numerical simulations and unmasked large-scale circulations and their reversals in canonical convection. At optimal orientations, the large-scale motions and core mixing events work against each other to achieve maximum heat transport. Our research findings have potential implications for climate studies and the development of thermal control strategies for device applications.
