Download or read book Flow Forming of Capillary Interfaces written by Vanessa Ruth Kern and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drop depositions are impacts where post impact the drop remains on the surface and its liquid/gas (LG) interface does not break apart. Our focus is on drop depositions in the capillary-ballistic regime. During drop impact, the falling drop's pre-impact energy transforms into fast-time scale motion of the three-phase contact-line (CL). The CL then comes to rest and the LG interface oscillates, viscously dissipating remaining energy on a slow-time scale. The energetics of drop deposition are characterized by high Reynolds number and moderate Weber number. Experiments are performed by impacting water/glycol drops onto substrates with varying wettability and hysteresis. The impacting event can be decomposed into three regimes: i) pre-impact, ii) inertial spreading, and iii) post CL pinning, which are conveniently framed using the theory of Dussan and Davis (1986). First we focus on the inertial spreading regime. Here we use high-speed imaging to resolve the stick-slip dynamics of the CL. The only form of dissipation during this fast-time scale is CL dissipation. Loss of energy occurs during a slip leg, and this observation is used to derive a closed-form expression for the 'post-pinning' energy. This prediction is independent of viscosity, only depending on the rest angle, equilibrium angle and hysteresis. This prediction agrees well with experimental observation for a range of liquid viscosities. We find this prediction of the post-pinning energy can be used to evaluate contact-line dissipation during inertial spreading. Next we focus on the drop's post-pinning dynamics. We show the LG interface vibrates with the frequencies and mode shapes predicted by Bostwick and Steen (2014), irrespective of the droplet's 'pre-impact' energy. Decay rates for the resonant modes are determined experimentally from FFTs of the interface dynamics. We find that the 'post-pinning' energy is independent of the 'pre-impact' energy and can be broken into modal components. Next we consider oblique drop impacts as an inverse problem framed analogously to mathematician Mark Kac's famous question 'Can one hear the shape of a drum?' (Kac, 1966). We find that knowledge of the drop's post-pinning LG frequency spectrum allows one to determine the rest angle and drop volume using theory for sessile drop oscillations (Bostwick and Steen, 2014). We also find that the substrate's inclination angle can be determined from the 'post-pinning' energy partitioning of the [1,1] and [2,0] vibrational modes. These results demonstrate that details of the impacting event can be known ex post facto without a priori knowledge of the experimental conditions. Last we discuss some future problems, including experiments to be performed on the International Space Station later this year. In microgravity capillary phenomenon occur with slower time scales and at larger length scales than their earth-based counterparts. Here we hope to expand our understanding of the fast moving CL by benefiting from this effective spatial/temporal magnification, alleviating earth based imaging restrictions.

Download or read book Soft Matter Self Assembly written by C.N. Likos and published by IOS Press. This book was released on 2016-07-14 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembly is one of the key concepts in contemporary soft condensed matter. It is an umbrella term which encompasses the various modes of spontaneous organization of micrometer-and submicrometer-sized particles into ordered structures of various degrees of complexity, yet it often relies on remarkably simple interactions and mechanisms. Self-assembly is one of the key principles used by nature to construct living matter, where it frequently takes place in a hierarchical fashion. This book contains the lectures from the Enrico Fermi summer school: Soft Matter Self-assembly, held in Varenna, Italy, in June and July 2015. The primary aim of the school was to cover the most exciting modern aspects of self-assembly in soft condensed matter physics, and to enable Ph.D. students and postdocs to engage with some of the most exciting and current topics in the physics of colloids through a series of mini-courses and seminars hosted by leading figures in the field. Subjects covered include: colloids with directional bonding; pathways of self-organization; self-assembly hydrodynamics; polymer structure and dynamics; liquid-crystal colloid dispersions; and self-organizing nanosystems. The proceedings also include two reprints from Reviews of Modern Physics, and will be of interest to both students and experts in the field.

Download or read book Transport Processes at Fluidic Interfaces written by Dieter Bothe and published by Birkhäuser. This book was released on 2017-07-13 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplinary research approach combining Applied Analysis, Numerical Mathematics, Interface Physics and Chemistry, as well as relevant research areas in the Engineering Sciences. The contributions originated from the joint interdisciplinary research projects in the DFG Priority Programme SPP 1506 “Transport Processes at Fluidic Interfaces.”

Download or read book Organs on chips written by Yu-suke Torisawa and published by MDPI. This book was released on 2020-05-27 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in microsystems technology and cell culture techniques have led to the development of organ-on-chip microdevices that produce tissue-level functionality, not possible with conventional culture models, by recapitulating natural tissue architecture and microenvironmental cues within microfluidic devices. Since the physiological microenvironments in living systems are mostly microfluidic in nature, the use of microfluidic devices facilitates engineering cellular microenvironments; the microfluidic devices allow for control of local chemical gradients and dynamic mechanical forces, which play important roles in cellular viability and function. The organ-on-chip microdevices have great potential to promote drug discovery and development, to model human physiology and disease, and to replace animal models for efficacy and toxicity testing. Recently, induced pluripotent stem (iPS) cells have been leveraged to develop organs-on-chips, which enable various types of organ models and disease models not possible with primary cells and cell lines. This Special Issue seeks to showcase research papers, short communications, and review articles that focus on: (1) microdevices to mimic or control cellular microenvironment; (2) microdevices to evaluate interactions between different organ models; (3) microdevices to maintain iPS cells or iPSC-derived cells; and (4) sensors and techniques to evaluate drug efficacy or toxicity.
