Evaporation and Mass Transfer Fundamentalsug of coffee. An evaporative heat transfer coefficient, h., is defined that can be included in any of the transient numerical simulations from earlier chapters (i.e., lumped 1-node, few node, multi-node). Evaporation is driven by concentration gradients, not a temperature difference, and defining an

Heat Transfer Fins (and Handles) “perfect” fin is one in which the temperature of the fin is the same everywhere as its base. In a real fin, the average temperature of the fin exposed to the fluid will be less than that, and therefore the fin transfers heat at a lower rate. If the fin is long enough, the temperature at the end of

Steady-State Conductionto that required to execute a step forward using an implicit transient solution. The method is first developed and applied to the mug of coffee, and then to a classic 2D problem. Extension to 3D is straightforward.

Convection Fundamentalsemperature that occur across the boundary layer. In heat transfer, there are two boundary layers that develop simultaneously; a momentum boundary layer and a thermal boundary layer. The retarding effects of viscosity occur within the momentum boundary layer. In fluid mechanics, the forces exerted by

Heat Exchanger Fundamentalsore comprehensive treatments of heat exchangers. In the end, practitioners and designers must learn how to interpret manufacturer specifications, which can be presented in various forms. A good fundamental understanding of the key principles involved facilitates that practice.
