Paper Published by Cui Zheng’s Research Group on Phase Change Heat Transfer at the Nanoscale Surface was Selected as the Cover Article in Langmuir

Recently, Professor Cui’s group from Shandong Institute of Advanced Technology, made progress on the research of micro/nano scale phase change heat transfer. The relevant research paper, titled Optimization Method for Grooved Surface Structures Regarding the Evaporation Heat Transfer of Ultrathin Liquid Films at the Nanoscale, was published as the cover article in Langmuir on March 24, 2020, which is one of the top interface journals of the American chemical society (ACS). Dr. Cao Qun is the first author of this paper, Professor Cui is the corresponding author.

This research revealed the general law of heat transfer enhancement of evaporation on the groove surfaces at the nanoscale by the molecular dynamic simulation. Based on the nonlinear positive correlation between the defined sectional area and the heat transfer performance, a method is developed to convert the maximum heat transfer and evaporation rate to a mathematical conditional extremum solution. By solving the Euler-Lagrange equation, the optimal structure of the groove surface can be obtained directly. The proposed method provides a new insight into the structure design for heat transfer enhancement of evaporation at the nanoscale.
