Simon Lance - University of Exeter
Convective motions are present in almost all astrophysical bodies, such as within the interiors of stars and planets, and must be sustained against any dissipative effects present. Historically, this dissipation has been treated as negligible. For the case of an incompressible fluid this is a valid assumption, however it has been shown both theoretically and numerically that for the case of highly compressible anelastic convection the amount of viscous dissipation present can in fact exceed the luminosity supplied to the fluid. The following work expands upon these findings numerically by using the python framework Dedalus to consider a layer of convective fluid contained within a Cartesian box on a tilted f-plane such that rotational effects can be considered.
