Introduction
Dr. Ching-Wen Lo received his BS degree from Department of Energy and Refrigerating Air-Condition Engineering at National Taipei University of Technology in 2011 and started his PhD study in 2012 in Department of Mechanical Engineering at National Chiao Tung University (NCTU) under the guidance of Prof. Ming-Chang Lu and Prof. Chi-Chuan Wang. In 2016, he served as a visiting scholar under Nanoscale Energy-Fluids Transport laboratory in Mechanical Engineering at Boston University directed by Prof. Chunhua Duan. He worked at NCTU in 2017 for his Postdoctoral under Prof. Ming Chang Lu in 2017. He awarded as the member of the Phi-Tau-Phi Scholastic Honor Society of the R. O. C. in 2017. He won the "Best PhD Thesis Award" by the Society of Theoretical and Applied Mechanics of the R. O. C. in 20

Article
Reducing the contact time (tc ) of a droplet impacting a solid surface is crucial in various fields. Superhydrophobic (SHB) surfaces are used to reduce tc at room temperature. However, at high temperatures, SHB surfaces cannot achieve tc reduction because of the failure of the coating materials or the Leidenfrost (LF) effect. Therefore, a surface t...
Article
Fouling causes numerous adverse effects on various types of systems. In addition, clean fouling on a solid surface is cost-intensive and time-consuming. Superhydrophobic (SHB) surfaces with a water-repellent property can potentially be used for antifouling. However, SHB surfaces lose their antifouling property at high temperatures because of the fa...
Article
Ice formation on various surfaces causes catastrophic consequences or enormous economic losses. Superhydrophobic surfaces with extreme water repellency were applied for removing ice efficiently; however, their practical applications are hindered by the fabrication of the complicated micro/nanostructures of the surfaces. In this work, we proposed us...
Article
Drop impacting on a superheated surface is of practical concern in several thermal systems. When the surface temperature is higher than the Leidenfrost point (LFP), a stable vapor cushion forms on the solid surface and the drop hovers over the thin vapor layer. This results in a drastic reduction in heat and mass transfer due to the thermally insul...
Article
Given the self-unbridging phenomenon, the confined liquid-film thickness, and the dragging motion observed on the 3D hybrid surfaces, enhanced condensation heat transfer on the 3D hybrid surface over a large subcooling (ΔTsub) range was achieved. In addition, the obtained heat flux of 655 ± 10 kW·m⁻² at ΔTsub ∼18 K exceeded the values in the litera...
Article
Fast drop bouncing is desired in numerous applications. However, it has never been realized on a superheated surface with concurrent contact boiling and the Leidenfrost effect (the so-called Janus thermal state). This is presumably because of the increased drop adhesion as a result of bubbling on a Janus surface. Nevertheless, on a hydrophilic SiNx...
Article
Condensation is an essential process in various industrial systems. Enhancing condensation by employing superhydrophobic (SHB) surfaces had drawn significant attention in recent years because of the emerging technology for surface engineering. However, the efficacy of SHB surfaces in condensation is controversy in the literature. The observed deter...
Article
Ice formation is a catastrophic problem affecting our daily life in a number of ways. At present, deicing methods are costly, inefficient, and environmentally unfriendly. Recently, the use of superhydrophobic surfaces has been suggested as a potential passive anti-icing method. However, no surface is able to repel frost formation at a very cold tem...
Article
Micro/nano (two-tier) structures are often employed to achieve superhydrophobicity. In condensation, utilizing such a surface is not necessarily advantageous because the macroscopically observed Cassie droplets are usually in fact partial Wenzel in condensation. The increase in contact angle through introducing microstructures on such two-tier roug...
Article
Condensation is a common phenomenon and is widely exploited in power generation and refrigeration devices. Although drop-wise condensation offers high heat and mass transfer rates, it is extremely difficult to maintain and control. In this study, the ability to spatially control heterogeneous nucleation on a superhydrophobic surface by manipulating...
