External flow boiling
Did you know?
Boiling process can be widely used in different industrial applications. In this two-phase heat transfer, the latent heat of vaporization of a liquid is used for dissipating large amount of heat flux. This feature makes boiling process suitable for thermal management of numerous thermal systems. See more Based on the nature of flow and operating temperature, boiling can be classified into different groups, which are discussed as follows: See more As mentioned earlier, critical heat flux is largest heat flux in the nucleate boiling mechanism and it can be identified by a sharp decrease in … See more There are a number of key parameters affecting the performance of the boiling heat transfer.

WebReaction in the flows: Passive flow in pipe or duct. reactive flow in the combustion; Phases of material: One or more phases can interact each during flow single-phase: Example – air flow through pipe Multi-phase flow like boiling or condensation; Other flow physics: Magnetic or electric field acting on the fluid WebIn flow boiling (or forced convection boiling), fluid flow is forced over a surface by external means such as a pump, as well as by buoyancy effects. Therefore, flow boiling is always accompanied by other convection effects. Conditions depend strongly on geometry, involving external flow over heated plates and cylinders or internal (duct) flow.
