Summary
This study is an attempt to attain a good understanding of boiling structures such as liquid-solid contact patterns and bubble structures near the boiling surface. This was accomplished by observing both the dynamic behaviour of liquid-solid contact from below the surface and the sectional views of bubbles in a quasi-two-dimensional boiling space. Results of the observation indicate that the boiling structures at heat fluxes near the critical heat flux point are different from the physical image given by the so-called macrolayer model. Based on this fact, the authors propose a new concept of the contact-line-length density describing the contribution of evaporating thin liquid layers to high-heat flux boiling heat transfer.
