WebConvective heat transfer between particles/parcels and the fluid, the details of which were previously explained, is the most important mechanism of heat transfer in fluidized bed systems. For general multiphase flows, however, particle–fluid–wall heat conduction can also play an important role if the walls of the reactor possess high heat ... WebIn residential heating, convection is the mechanism by which heat is lost by warm air leaking to the outside when the doors are opened, or cold air leaking into the house through the cracks or openings in walls, windows, or doors. When cold air comes in contact with the heater in a room, it absorbs the heat and rises.
