I have a closed system with a heated plate submerged in a liquid (2D). A heat flux is applied to the plate walls and the walls of the enclosure have a constant temp BC. The Boussinesq model is used and confirmed to be valid since my temperature gradient is small.nIn the user guide it states If the density is assumed constant or if it is derived from a profile function of temperature, the operating pressure is not used in the density calculation. nSince the Boussinesq model treats density as a constant value in all equations except for the buoyancy term in the momentum equation (which is not a function of pressure), does the operating pressure defined in Operating Conditions effect the solution? n<\/p>\n","protected":false},"template":"","class_list":["post-49707","topic","type-topic","status-closed","hentry","topic-tag-boussinesq-approximation","topic-tag-fluent","topic-tag-operating-pressure"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
