Today there is a great interest in micro-scale multiphase fluid flow. In the paper, numerical simulation of two-phase flow inside 3 mm minichannel was carried out. The liquid- gas interface captured using level-set method. During calculation, stabilization and reinitialization level set function performed order to obtain proper accuracy simulation. Incompressible Navier-Stokes equations were solved COMSOL Multiphysics® on two-dimensional mesh. process formation different patterns has been...
The bifurcation of slugs to bubbles within two-phase flow patterns in a minichannel is analyzed. (water-air) occurring circular horizontal with diameter 1 mm examined. sequences light transmission time series recorded by laser-phototransistor sensor analyzed using recurrence plots and quantification analysis. Recurrence parameters allow the be found. On changing water rate we identified partitioning or aggregation bubbles.
Abstract By increasing a water flow rate of the two-phase (air–water) through minichannel, both partitioning air slugs into bubbles different sizes and small aggregation larger were identified. These phenomena studied in detail by using corresponding sequences light transmission time series recorded with laser-phototransistor sensor. To distinguish any instabilities along their break-ups aggregations, recurrence plots quantification analysis applied.
The churn-to-slug flow bifurcations of two-phase (air-water) patterns in a 2mm diameter minichannel were investigated. With increasing water rate, we observed the transition slugs to bubbles different sizes. process was recorded by digital camera. sequences light transmission time series laser-phototransistor sensor, and then analyzed using recurrence plots quantification analysis (RQA). Due volume dependence velocities, formation periodic modulations laser signal.
The paper investigates the dynamics of bubble departures from a glass nozzle submerged in tank filled with distilled water. Air pressure and liquid flow inside are simultaneously recorded using data acquisition system high speed camera. recurrence plot cross methods used to identify loss synchronization between air fluctuations depth during chaotic departures. We claim that penetration is suppressed experimental results show agreement numerical findings. demonstrate non-linearities processes...
Abstract The synchronization between the air pressure fluctuations and depth of liquid penetration into nozzle during bubble departures was investigated using joint recurrence quantification analysis. In experiment, bubbles were generated from a glass distilled water. During analysis, recurrent rate coefficients calculated for changes in gas supply system. study conducted by two volume flow rates, i.e. 0.023 l/min 0.026 l/min. rates selected so that appearance disappearance period clearly...
