The main goal of this correlations-based modeling investigation is to undertake a preemptive analysis on expected measurement values (of selected flow variables) that may be realized during the implementation/completion of the ongoing experimental endeavors dealing with non-pulsatile steady operations of the innovative flow boiler. The correlation models do not accurately predict the heat transfer coefficients or pressure drops due to the assumptions lumped into the development of the correlations. At the conclusion of the investigation, a tool was created that provides rough order of magnitude estimates of pressure drop and local heat transfer rates. The approach is also recommended for …

Several modern-day cooling applications require the incorporation of mini/micro-channel shear-driven flow condensers. There are several design challenges that need to be overcome in order to meet those requirements.
The difficulty in developing effective design tools for shear-driven flow condensers is exacerbated due to the lack of a bridge between the physics-based modelling of condensing flows and the current, popular approach based on semi-empirical heat transfer correlations. One of the primary contributors of this disconnect is a lack of understanding caused by the fact that typical heat transfer correlations eliminate the dependence of the heat transfer coefficient on the method of …
