for evaluation of citric acid and citrate effects on bovine epididymal protoplasmic droplets, fifty bovine testes were collected in the october 2007 till june 2008 from urmia slaughterhouse and transported to the laboratory in a cool container filled with 5 °c ice pack. caudal epididymis was incised and sperm cells were put into petri dishes containing hams f10 media with 10% fetal calf serum (...

The behavior of droplets collision in a flash evaporation ambient widely exists various fields. In this work, the deformation analysis and thermal models were established under condition via computational fluid dynamics (CFD) method. First, effects initial temperature velocity on heat mass transfer during considered. Then, morphology change liquid phase, change, their influencing factors drople...

In this study, we investigated electrowetting on the dielectric-induced splitting behavior of droplets placed in a Hele–Shaw cell. The deformation droplet was experimentally observed under various applied voltages. A theoretical model proposed to express by balancing surface tension, viscous force, and pressure acting droplet. effect dynamic contact angle considered used estimate capillary forc...

Abstract Droplet impacts on superhydrophobic surfaces may result in complete bouncing, with the absence of contact hysteresis and viscous dissipation leading droplet to fully rebound off surface. This usually happens retraction phase, when retracts back after reaching a maximum spread diameter. Here, we present experimental evidence bouncing phenomenon where sessile hydrophobic surface bounces ...

Abstract A compound droplet subject to three-dimensional oscillatory shear flow is studied using a three-phase lattice Boltzmann model. Firstly, focusing on low values of capillary number (Ca) where the eventually reaches steady-state condition, we study effect period, viscosities inner and outer fluids droplet, wall confinement Ca behavior. As period increases, maximum deformation parameters g...
