WebThe direction of heat flow is always from the fluid with higher temperature to lower temperature. The mechanism of heat transfer in a heat exchanger is a combination of conduction and convection. Flow configuration of heat exchangers is countercurrent, co-current or parallel flow, cross flow, and hybrid flow.

WebHeat exchangers are devices that transfer thermal energy from one fluid to another without mixing the two fluids. The fluids are usually separated by a solid wall (with high thermal conductivity) to prevent mixing, or they may be in direct contact. Heat exchangers are typically classified according to flow arrangement and type of construction. WebHeat Exchanger Effectiveness (NTU method) If more than one of the inlet and outlet temperature of the heat exchanger is unknown, LMTD may be obtained by trial and errors solution.
