It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number. [1] It's believed to be named after Franz Grashof.
WebNusselt number (Nu) on the other hand is an non dimensional heat transfer coefficient. It gives the comparison between the conduction and convection heat transfer rates.
