See also: Convection. In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas.These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell.ee also: Convection. In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas.
Convection is the transfer of heat energy between a solid surface and the nearby movement of a liquid or gas (such as air). As fluid motion goes more quickly the convective heat transfer increases. The presence of bulk motion of fluid enhances the heat transfer between the solid surface and the fluid.
