RESEARCH

The following highlights ongoing research activities, applications and latest findings:

Microporous Coating - A family of coatings which are painted on surfaces. They produce pool boiling heat transfer coefficients that are up to five
times those of uncoated surfaces.

Thermally Conductive Microporous Coating (TCMC) - All metal microporous coating. It is bonded to surfaces by soldering. Produces pool
boiling heat transfer coefficients that are four times those on uncoated surfaces. Increases CHF over two times.

TCMC in Flow Boiling - Results of tests over a 10mmx10mm coated heater with pure saturated FC-72.

TCMC in Spray Cooling - Results of tests over a 10mmx10 mm coated heater and a 30mmx30mm heat spreader with gassy subcooled FC-72.

High Temperature TCMC (HTCMC) - All metal microporous coating which is brazed to the surface.

Nanofluid Boiling - First demonstration of doubling of CHF by a low concentration nanofluid and first demonstration of transient behavior of nanofluid boiling.

Nanocoatings in Pool Boiling - Demonstration that nanocoating and not the nanofluid itself causes CHF increase. Correlations of CHF to wettability
characteristics of the nanocoating. Experimental proof of mechanism of nanocoating formation in pool boiling.

Wettability & Wickability Enhancement - Demonstrations of increase of wettability and wickability through microporous coatings and nanoporous coatings.

Interface Material Test - Example from a parametric study on thermal interface materials.

Liquid Cooling Module - Example of a liquid cooling module which serves as a very efficient heat spreader. Other versions of this type of module
have and are being developed.

Measurement Technique - By this technique contributions from latent and sensible heat to boiling heat transfer can be experimentally measured.

Spray Cooling Enhancement - Example of very large enhancement of spray cooling achieved by the use of the microporous coating.
