1. On the influence of the heat transfer at the free surface of a thermally-driven rotating annulus

Author

Subjects

Abstract

Experiments on rotating annuli that are differentially heated in the radial direction have been largely contributing to a better understanding of baroclinic instabilities. This configuration creates waves at a laboratory scale that are related to atmospheric circulations. Pioneer studies in baroclinic tanks have shown that experiments with low aspect ratios are more suitable to reproduce small-scale inertia gravity waves, but these tanks have a larger free surface, which leads to higher interactions with its surrounding environment. Considering the heat transferred through the free surface, the present work investigates its impacts on the baroclinic instability using direct numerical simulations (DNS).

Abstract

A numerical method to solve transfer equations in a thin phase change material (PCM) layer in contact with a solid material or a fluid is presented. This numerical method is applied to predict the heat transfer in a lid-driven cavity which one of its vertical plane walls is covered with a thin layer of PCM. The mathematical modeling and numerical method will be first presented, and then the boundary condition associated to the PCM wall is formulated in term of “Signorini boundary condition”. The numerical method proposed to solve this formulation is validated by a test case.
