Numerical Study of the Controlled Droplet Breakup by Electric Fields inside a Microfluidic Flow-focusing Device
Droplet-based microfluidics has received extensive research interests due to its superior control over the fluid flow. Conventional passive microfluidic flow-focusing devices confront difficulties in controlling droplet sizes in dripping regime especially when the dispersed phase has a large viscosity. External electric fields have been reported as an effective tool to manipulate droplet breaku...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولThe Effects of Shock Strength on Droplet Breakup
The breakup of droplets occurs in the combustion of multiphase mixtures and the atomization of liquid jets. Most experiments studying droplet breakup have used the passage of a normal shock to provide a step change to uniform flow conditions. In the late 1950s, Engel [2] investigated how water droplets of various sizes broke up in the flow behind air shocks of different strengths. The subsequen...
متن کاملNumerical simulations of the early stages of high - speed droplet breakup
Experiments reported in the literature are reproduced using numerical simulations to investigate the early stages of the breakup of water cylinders in the flow behind normal shocks. Qualitative features of breakup observed in the numerical results, such as the initial streamwise flattening of the cylinder and the formation of tips at its periphery, support previous experimental observations of ...
متن کاملDroplet Breakup in High-Speed Gas Flows
Numerical simulations are performed to study the breakup of water cylinders in the flow behind normal shocks. The computational setup is similar to previous experiments (Igra and Takayama, 2001, 2003). We examine the qualitative features of the so-called stripping breakup observed in the numerical results. Two interesting flow features are discussed: the existence of recirculation regions and a...
