Abstract In this work, the flow of immiscible fluids in a PMMA microchannel 300 μm wide and 600 deep was investigated experimentally. Dyed de‐ionized water kerosene were selected as test fluids. Flow patterns observed by using CCD camera identified examining video images. obtained at T‐junction are presented. Superficial velocities varied between 9.26 × 10 −4 ∼ 1.85 m/s for 2.78 kerosene. The formation mechanism slug, monodispersed droplet populations studied. Weber numbers kerosene, We KS...
Abstract In this work, the mass transfer characteristics of immiscible fluids in two kinds stainless steel T‐junction microchannels, opposing‐flow and cross‐flow T‐junction, are investigated experimentally. Water‐succinic acid‐ n ‐butanol is chosen as a typical example liquid–liquid two‐phase process. our experiments, mixture velocities phases varied range from 0.01 to 2.5 m/s for 0.4 mm microchannel 0.005 2.0 0.6 microchannel, respectively. The Reynolds numbers vary between 19 650. overall...
Abstract Flow distribution and mass transfer characteristics during CO 2 ‐water flow through a parallel microchannel contactor integrated with two constructal distributors have been investigated numerically experimentally. Each distributor comprises dichotomic tree structure that feeds 16 microchannels hydraulic diameters of 667 μm. It was found could ensure nearly uniform gas–liquid at high gas rates where the ideal pattern slug‐annular flow. Nevertheless, small slug flow, significant...
The development of highly efficient processes for the cycloaddition CO2 with epoxides to produce five-membered cyclic carbonates is a very attractive topic. In this work, propylene oxide (PO) and give carbonate (PC) studied in microreactor using HETBAB ionic liquid catalyst. performance evaluated by studying effects different operating conditions, including reaction temperature, pressure, residence time, molar ratio CO2/PO, catalyst concentration PO. process characteristics concerning...
Intensification of liquid mixing was investigated in domestic fabricated ultrasonic microreactors. Under the field, cavitation bubbles were generated, which undergo vigorous translational motion and surface oscillation with different modes (volume, shape oscillation, transient collapse). These phenomena induce intensive convective reduce time from 24–32 s to 0.2–1.0 s. The performance decreases channel size, due weaker activity smaller channel. energy efficiency is comparable that...
The effects of ultrasound on the hydrodynamic and mass transfer behaviors immiscible liquid–liquid two‐phase flow was investigated in a domestic ultrasonic microreactor. Under irradiation, cavitation bubble generated underwent violent oscillation. Emulsification phases initiated by virtue oscillating bubbles shuttling through water/oil interface. pressure drop found to decrease with increasing power, maximum decrement ratio 12% obtained at power 30 W. behavior characterized extraction...
Abstract In this experiment, the inert gas is used to agitate two immiscible fluids in microchannels. The mass transfer performances with or without agitation are investigated. 30% TBP (in kerosene)‐acetic acid‐water chosen as testing system, and nitrogen agitating gas. superficial velocities of liquid–liquid phases phase varied range from 0.02 1.2 m/s, 0 3.0 respectively. microchannels, enough intensity, high dispersion between liquid can be obtained. overall volumetric mean coefficients...
Ultrasonic microreactors were used to intensify gas‐liquid mass‐transfer process and study the intensification mechanism. Fierce surface wave oscillation with different modes was excited on bubble. It found that for slug bubbles confined in smaller microchannel, oscillations require more ultrasound energy excite due confinement effect. Cavitation microstreaming two toroidal vortices observed near oscillating bubble by a streak photography experiment. Surface at interface increases specific...
The combination of ultrasound and microreactor is an emerging promising area, but the report designing high-power ultrasonic (USMR) still limited. This work presents a robust, highly efficient USMR by directly coupling plate with Langevin-type transducer. designed as longitudinal half wavelength resonator, for which antinode plane highest sound intensity located at microreactor. According to one dimension design theory, numerical simulation impedance analysis, maximum power 100 W resonance...
