Abstract
The study deals with unsteady heat transfer between a spherical encapsulated nanoparticle with a phase transition material as a core and the ambient medium. The calculations take into account the Kapitsa’s contact thermal resistance at the nanoparticle interface. It was demonstrated that this phenomenon can be critical for heat transfer in nanofluids.
