I'm a materials guy who has made thousands of tons of stainless steel for pipe and tube. My question is, would there be value in a micro surface finish on heat exchanger surfaces (one that does alter dimensions or change traditional surface appearance; not a coating) which causes low surface energy, therefore hydropohobicity? It has been widely accepted that this would cause drop-wise condensation and nucleation sites for boiling with a many-fold increase in heat transfer rates, but I would like to hear what the real practioners in the field think.
This was posted on another forum, but it was suggested I poll this group.
