WebFor heat transfer in a tube at low flow velocity, heat conduction can be dominant, while at higher velocities, forced convection will at some point become dominant. In general, the heat... WebConvection is the transfer of heat by the movement of a fluid or gas. It occurs when a fluid is heated, causing it to expand and become less dense. The less dense fluid then rises, while cooler, denser fluid sinks. This creates a circulating pattern, where heat is transferred from one part of the fluid to another by the motion of the fluid.
