High-Resolution Experimental Measurements and Mechanistic Modelling of Saturated Cryogenic Pool Boiling Heat Transfer
… lead to pressurization of components like fuel line and tanks, cause two-phase flow instabilities during fuel transfer, or significantly reduce the usable amount of cryogenic fuel. Progresses in multiphase computational fluid dynamics (mCFD) can be leveraged to predict the two-phase flow …

Experimental Investigation of Subcooled Flow Boiling and CHF at Prototypical Pressures of Light Water Reactors
… aspects of bubble departure, microlayer and triple contact line evaporation, boiling parameters (i.e. nucleation site density, bubble departure frequency, wait and growth times), heat flux partitioning and departure from nucleate boiling. The results reveal that in high pressure flow boiling …

Experimental Investigation of Critical Heat Flux Enhancement on Engineered Surfaces with Infrared Thermometry
… a certain distance (<1 mm) from the apparent triple contact line. This wicking distance, is found to depend on the local heat flux which is limited by thermal diffusion in the heater substrate. We can reproduce these observations with mechanistic models describing the evaporation of the …

Fluid Dynamics in Liquid Entry and Exit
… on a solid object. However, as the behavior of a triple contact line has not been understood on a sinking object, previous studies were limited to the special case of hydrophobic object to fix the contact line. Moreover, a more recent study pointed out the important role of contact line behavior …

Fluctuations, Phase Separation and Wetting Films near Liquid-Gas Critical Point
… was heated and, as a result, a low contrast line appeared on the wetting film that corresponded to a sharp change in the thickness of the film. A large mechanical response was observed in response to the cell heating and we present quantitative results about the receding contact lines. It is …
