Curvature dependence of heat transfer at a fluid-solid interface
A Dinler and RW Barber and SK Stefanov and DR Emerson, PHYSICAL REVIEW E, 98, 033104 (2018).
This study reports an opposing effect of curvature on the interfacial heat transfer, which implies a monotonic increase in the temperature jump over a convex surface and, conversely, a monotonic decrease in the temperature jump over a concave surface, as the curvature of the surface increases. The study shows that this effect is present at both gas-solid and liquid-solid interfaces. The curvature dependence of the interfacial thermal conductance is also investigated and the opposing effect is elucidated by the change in the thermal conductivity of the fluid-solid interface.
