Possibility of the application of microstructures in heating and ventilation systems

Microstructural coatings may by successfully applied in phase-change heat exchangers to enhance heat transfer. They can be used in heating and ventilation systems as presented in the literature review. The test results of boiling heat transfer prove that it is possible to significantly increase heat flux comparing to the smooth surface if porous microstructures are applied. The measurements were conducted on the non-isothermal surface of the fin. Distilled water was used as the working fluid.
