WebApr 19, 2006 · We consider the free-convective flow from a heated sphere, in the Boussinesq approximation, at high Grashof number. The characteristics of the boundary layer close to the surface of the sphere are evaluated numerically, and the eruption of the fluid from the boundary layer into the plume above the sphere is discussed. WebIn October 1844 Franz Grashof quit school to start studying metallurgy at the royal vocational institute in Berlin, where he studied mathematics, physics and mechanical engineering. From 1847 to 1848 he interrupted his studies to voluntarily serve for the military. To serve his country he aimed at becoming a marine officer.

WebThe Grashof number is a dimensionless number named after Franz Grashof. The Grashof number is defined as the ratio of the buoyant to a viscous force acting on a fluid in the velocity boundary layer. Its role in natural convection is much like that of the Reynolds number in forced convection. Natural convection is used if this motion and mixing ...

WebEssentially, the Grashof number is a ratio of buoyant forces to viscous forces. When Gr >> 1, the viscous force is negligible compared to the buoyancy and inertial forces. When buoyant forces overcome the viscous forces, the flow starts a transition to the turbulent regime. For a flat plate in vertical orientation, this transition occurs around ...
