The numerical investigation of drop deformation and breakup under simple shear is a basis for theoretical studies of emulsification and mixing. A three-dimensional Couette flow without gravity is considered; the matrix liquid is bounded at the top and bottom by two parallel horizontal plates and the liquid drop is suspended there. The boundaries move horizontally, and generate a simple shear fl...

In this work, an improved multi-channel cold plate is designed based on a traditional for enhancing its performance. Taguchi experimental design, grey relational analysis and of variance are applied to investigate the effects multi-factors performance plate. addition, j/f factor employed evaluate overall Results suggest that highest when mass flow rate, channel number, ambient temperature obliq...

The pheromone drop test is a simple and robust behavioral assay to quantify acute avoidance of pheromones in C. elegans, and the suppression of avoidance by attractive pheromones. In the pheromone drop test, water-soluble C. elegans pheromones are individually applied to animals that are freely moving on a large plate. Upon encountering a repellent, each C. elegans animal may or may not try to ...

An experimental investigation of hydrodynamics gas-solid flow is carried out by engaging different designs air distributor plates. analysis three plates, i.e., perforated, 45° slotted and novel hybrid plate, revealed the difference in pressure drop minimum fluidization velocities (Umf) for varying input operational variables. Umf found to be lowest perforated highest whereas plate plate. The bu...

Microfluidic devices enable massive parallelization of sample manipulation and delivery, but a similarly parallelized and integrated optical detection system does not yet exist. Standard large numerical aperture wide field or scanning optical systems are not capable of the large field of view and detection sensitivity required to collect fluorescence from parallel arrays of microfluidic devices...

We report on experimental studies of spatio-temporally heterogeneous stickslip motions in the sliding friction between a hard polymethyl methacrylate (PMMA, plexiglass) block and a soft poly-dimethyl siloxane (PDMS, silicone) gel plate. We perform experiments on two PDMS gels with different viscoelastic properties. For the less viscous gel, large and rapid events are preceded by an alternation ...

A drop impingement on a hot surface is known as an effective way for heat removal. The present work uses VOF (volume of fluid) model to simulate the flow behavior and temperature distribution 50 °C heated plate while relatively cold water impinging. at zone used examine transient transfer coefficients using single double drops conditions. spreading factor tested in both cases. test rig built ve...

The technology of large surface thermal management pouch cells was studied and discussed by means simulation. With management, two are managed a single cold plate. First, the pressure drop plate simulated velocity distribution flow field observed. cooling performance to cell then studied, low-temperature heating ability analyzed. Through analysis, it can be concluded that effectively quickly co...

The purpose of this study is to investigate the two-phase flow field characteristics in flat plate heat exchangers. The main objectives are the causes of plate wetting/drying, measurement of fluid flow field characteristics, and the effects of enhanced plate passageways. Three types of passageways are being investigated: smooth-walled passageways, chevron-style passageways, and embossed (bumpy)...

This paper analyzes the configurations of shapes that shows a spacelike liquid drop in Minkowski space deposited over a spacelike plane Π. We assume the presence of a uniform gravity field directed toward Π and that the volume of the drop is prescribed. Our interest are the liquid drops that are critical points of the energy of the corresponding mechanical system and we will say then that the l...
