# Natural Convection between Two Vertical Plates

Natural Convection between Two Vertical Plates

The dimensionless vertical velocity inside two vertical plates at distance and temperatures and is computed for specified Grashov number , where is the velocity , is the distance in meters, is the kinematic viscosity in /s, is the gravitational acceleration in , and is the volumetric coefficient of thermal expansion in .

The frame ticks change with Grashov number , which conveniently lets you observe that the shape of the velocity distribution did not change.
