Condensation studies using cross-corrugated polymer film compact heat exchanger

Heat transfer has been examined in a polymer film compact heat exchanger between cross flowing liquid and gas. Condensation of water vapour through a non-condensable gas was used to supply heat through a corrugated poly-ether-ether-ketone (PEEK) film to a cooling liquid. Measurements of heat transfer rates in the system indicated overall heat transfer coefficients in the range of 50–300 W m−2 K−1 were achieved. Visual analysis and pressure drop measurements were used to provide insight into the fluid flow and the models used for heat transfer.
