Research Title:

Numerical modelling of novel heat exchanger material.

Research description:

A numerical study (lattice Boltzmann method) investigates a new heat exchanger material existing of a fine metallic structure, e.g. a metallic foam. The surface of this material carbon is covered with carbon nano fibers (CNFs). These fibers influence the fluid flow, and enlarge the heat exchanging surface. Preliminary experimental research has shown that the presence of these CNFs can enhance heat transfer by 40%. This depends very much on the CNFs density and on the structure of the CNFs itself. This numerical study gives directions in optimizing this new material.
