Imbibition dynamics in an open-channel capillary with holes

Guan-Yu He et al.

Summary: This study investigates capillary imbibition into a two-rail channel with/without holes using many-body dissipative particle dynamics (MDPD). The effects of channel height, channel width, hole size, and surface wettability on the imbibition rate are examined. The results show that the penetration rate increases with decreasing channel height or increasing channel width. However, the presence of holes in the channel slows down the wicking dynamics and leads to different outcomes depending on the size and position of the holes.

Edge wetting: Steady state of rivulets in wedges

Nikolai Kubochkin et al.

Summary: The geometry of rough, textured, fractured, and porous media is topologically complicated. This paper shows that steady-state rivulets can be formed in open wedge-like channels when surface forces are taken into account. A simple model based on the disjoining pressure approach is presented and the shape of rivulets in wedges is analyzed.

Estimation of the thermohydraulic performance of a microchannel heat sink with gradual and sudden variation of the flow passage

A. Rajalingam et al.

Summary: In this study, the limitations of high pumping power and uneven temperature distribution in a microchannel heat sink (MCHS) were optimized through modification of channel geometry. The results showed that the overall performance index could be improved by introducing sudden expansion and sudden contraction, as well as connecting channel sections with different cross-sectional areas.

Imbibition dynamics and steady flows in graphene nanochannels with sparse geometric and chemical defects

Yi-Ting Cheng et al.

Summary: In this study, the imbibition dynamics and steady flows of water in graphene nanochannels with sparse defects were explored using molecular dynamics. It was found that geometric defects and chemical defects have different effects on the water contact angle and velocity distribution, with chemical defects having a more significant impact. Moreover, sparse defects also had a remarkable influence on the imbibition dynamics of graphene nanoslits.

Thermally assisted mobility of nanodroplets on surfaces with weak defects

Yu-Hao Tsao et al.

Summary: In this study, thermal assisted motion of nanodroplets on nanorough surfaces was investigated using Many-body Dissipative Particle Dynamics. The experiments showed a decrease in slip length with increasing defect density, a linear relationship between sliding velocity and driving force, and absence of contact line pinning. Simulation results agreed well with theoretical predictions, showing a two-dimensional Brownian motion of nanodroplets and a relationship between diffusivity and mobility consistent with the Einstein relation, suggesting thermal fluctuations can overcome contact line pinning caused by weak defects.

Spontaneous spreading of nanodroplets on partially wetting surfaces with continuous grooves: Synergy of imbibition and capillary condensation

Kang-Ching Chu et al.

Summary: The wetting behavior of nanodroplets deposited on hydrophilic textured surfaces with discontinuous and continuous grooves was studied using dissipative particle dynamics. The transition from partial to total wetting can occur on hydrophilic surfaces as the surface textures change from discontinuous to continuous grooves. The spreading of nanodroplets along continuous grooves can be characterized by apparent radius and groove radius, influenced by factors such as spontaneous imbibition and capillary condensation.

Rivulets of finite height

Felix Gerlach et al.

Summary: This study examines two situations where capillary rivulets rise only to a finite height, one due to a vertical corner being dipped into a liquid pool, and the other due to not meeting the Concus-Finn criterion leading to a finite rise height. Experiments and theoretical expressions were conducted for both cases, with Surface Evolver simulations used to complement the results for contact angles exceeding the Concus-Finn criterion.

A Review of Capillary Pressure Control Valves in Microfluidics

Shaoxi Wang et al.

Summary: Microfluidics provide controlled microenvironments with various functions, with capillary pressure control valves becoming popular for liquid control without the need for affiliated equipment. The analysis of CPCVs focuses on surface tension, contact angle, and microchannel shape parameters, aiming to simplify automation and expand the use of microfluidic networks. The review explores how CPCVs streamline processes, work with different driving modes, and enable controlled sampling and delivery in microfluidic fields.
