A proposed correlation for critical flow rate of water flow

Nuclear Engineering and Technology, 2015
A new correlation predicting the idealized critical mass-flow rates of water for subcooled and saturated liquid water including two-phase water flow was developed for a wide range of upstream stagnation pressures (e.g., 0.5–20.0 MPa).

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

Advanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...
