Sinopsis

The spectacular heat transfer enhancement revealed experimentally in nanofluids suspensions is being investigated theoretically with the aim of explaining the possible mechanisms that lead to such impressive experimental results. In particular, the possibility that Dual-Phase-Lagging heat conduction in the heterogeneous medium (nanofluid suspension) could have been the source of an apparent excessive improvement of the effective thermal conductivity of the suspension is shown to provide a viable explanation. The investigation of alternative possibilities are being discussed but more work is needed prior to reaching an ultimate conclusion.
