Heat transfer enhancement and critical heat fluxes in boiling of microfinned surfaces

A brief review is presented of experimental investigations of heat transfer enhancement during boiling on surfaces with nano- or microstructure. Distilled water boiling on microfinned surfaces made by deforming cutting was investigated. It was found that, for distilled water boiling on these surfaces with 3D microfinning (having an interfin gap of u = 120–180 μm, a microfin height of h = 340–570 μm, and a microfin pitch of w = 240–400 μm), heat transfer increased by a maximum factor of 4 to 5 as compared with that on smooth surfaces. Critical heat fluxes increase by a factor of up to 6 as compared with boiling on smooth surfaces.

Heat transfer during the boiling of liquid on microstructured surfaces. Part 2: Visualization of boiling and critical heat fluxes

Results from visualization of boiling process and experimental study of critical heat fluxes on microstructured surfaces are presented. The studied surfaces were obtained using the deforming cutting method and have different design shapes and sizes. Mechanisms of heat transfer enhancement are substantiated. A factor of 4.1 higher value of critical heat flux is obtained.
