Title: Bio-inspired Functional Surfaces for Enhanced Condensation Heat Transfer

Speaker: Prof. Xuemei Chen, Nanjing Univ Sci & Technol

Date/Time: 9:30 AM, Mar. 23 (Fri.)

Location: Room 202, Lujiaxi Building

Abstract: 

Vapor condensation plays a key role in a wide range of industrial applications including power generation, thermal management, water harvesting and desalination. Over the past few decades, extensive efforts have been made to enhance condensation heat transfer enabled by traditional homogeneous superhydrophobic surfaces, however, fast droplet nucleation and efficient droplet departure as well as low interfacial thermal resistance are important factors that determine the thermal performances of condensation; these properties have conflicting requirements on the structural roughness and surface chemistry of the condensing surface or condensation modes (e.g., filmwise vs dropwise). In this talk, I will discuss our recent efforts in tailoring surface/interface morphology and chemistry for enhanced condensation heat transfer.
