    Home Plate is a light-toned plateau approx m in diameter within the Inner Basin of the Columbia Hills in Gusev crater on Mars. It is the most extensive exposure of layered bedrock encountered by Spirit to date, and it is composed of clastic rocks of moderately altered alkali basalt composition, enriched in some highly volatile elements. The heat transfer in multilouvered fins is influenced by three f actors: a) duct versus louver directed flow [3,4]; b) thermal wake interference [5]; c) flow instabilities and transport of coherent vorticity in the vicinity of the louver surface [6]. These three phenomena can be captured with good precision in two -dimensional unsteady simulations.
