Ouzo effect represents a typical spontaneous emulsification process, which is widely used in many fields such as chemical industry, biomedicine and fabrication of novel materials. This work attempts to clarify the influence sound field container-free conditions on by combining transition with action field. We compare dynamic process performing experiments glass slide an acoustic levitator, resp...

When particles adsorb at a fluid/fluid interface at a sufficiently high concentration, the interface loses mobility and displays solidlike characteristics, a phenomenon called "interfacial jamming". Jamming can arrest interfacial tension-driven morphological coarsening in liquid/liquid or gas/liquid systems and therefore stabilize two phase morphologies with unusual interfacial shapes, for exam...

In slurry bubble column reactors, catalyst particles may adhere to gas bubbles. Thus, mass transfer limited reactions can be significantly improved either by increasing G-L mass transfer coefficient kL or specific surface area a. The scope of this work is to study the influence of model parameters on coalescence and G-L mass transfer, in order to develop new rules for design and scale-up of slu...

The fundamental unit of large scale software construction is the component. A component is the fundamental user interface object in Java. Everything you see on the display in a java application is a component. The ability to let users drag a component from the Interface and drop into your application is almost a requirement of a modern, commercial user interface. The CBD approach brings high co...

In this paper we analyze the effects of the following phenomena associated with the thermocapillary migration of a drop. The first is the influence of Newtonian surface rheology of the interface and the second is that of the energy changes associated with stretching and shrinkage of the interfacial area elements, when the drop is in motion. The former occurs because of dissipative processes in ...

در این پایان نامه هدف شبیه سازی عددی حرکت و تغییر شکل قطره بر روی سطح و بررسی مدل های کشش می باشد. مطالعه در مورد قطرات در علوم و مهندسی دارای کاربرد و اهمیت زیادی است. یکی از این مسایل وجود قطرات بر روی سطح کاتدی در پیل های سوختی دارای غشاء مبادله کننده ی پروتون می باشد. در این پیل های سوختی مدیریت آب اهمیت ویژه ای دارد و وجود قطرات آب باعث کاهش عملکرد پیل سوختی می شود. بنابراین با استفاده از ...

The structure of an oil/water emulsion is known to depend on its preparation method. Here, we test whether the preparation protocol can be used to control the morphology of ‘‘model’’ blends of immiscible polymers compatibilized by a diblock copolymer. Two preparation protocols were tested. In the ‘‘double blending’’ protocol, a droplet-matrix blend was blended with additional drop-phase fluid. ...

In order to obtain a better understanding of short-range (SR) and long-range (LR) nanoparticle (NP) interactions during the self-assembly of dodecanethiol-coated Au NPs in toluene via drop drying, we have investigated the dependence of the island density, scaled island-size distribution (ISD), and scaled capture-zone distribution (CZD) on coverage, deposition flux, and NP size. Our results indi...

We present an adaptive remeshing algorithm for meshes of unstructured triangles in two dimensions and unstructured tetrahedra in three dimensions. The algorithm automatically adjusts the size of the elements with time and position in the computational domain in order to resolve the relevant scales in multiscale physical systems to a userprescribed accuracy while minimizing computational cost. T...
