This work presents an experimental and analytical study on the convective condensation in small diameter channels. Two different types of heat exchangers were tested: one with conventional channels and one where a porous boundary was present. Tests were performed for low and high flow rates and two saturation temperatures. For low flow rates, the condensers with small diameter channels presented excellent heat dissipation capability, with high Nusselt numbers. For the condenser with a porous boundary, the Nusselt number was even higher when compared with the condenser with conventional...
