Grashof reynolds forced or free convection
WebGrashof Number You see this number and you should think of natural or free convection. The Grashof number is the ratio of buoyancy forces to the viscous forces. In natural convection the Grashof number plays the same role the is played by the Reynolds number in forced convection. http://www.mhtl.uwaterloo.ca/courses/ece309_mechatronics/lectures/pdffiles/ach6_web.pdf
