“…Consequently, micro-reactors are supreme for conducting operations even with highly exothermic reactions or under supercritical conditions (Nauman 2008;Benito-Lopez et al 2008;Marre et al 2012). Besides all processing benefits for micro-reactor, the axial dispersion effects associated with the parabolic flow profile of typical micro-channel contribute to a broader RTD (Chang 2013).…”

“…In numerous applications in the fine chemical and pharmaceutical industries [15][16][17][18], the properties of the final product depends greatly on mass transfer to the catalyst particle surface [19]. Due to the laminar flow conditions prevalent in microchannels, the transport of reactants to the catalyst surface is often limited by diffusion due to the formation of thick hydrodynamic and mass transfer boundary layers around catalytic particles [20].…”

AbstractThe effect of periodic changes in particle velocity on mass transfer to the reacting surface of a magnetic particle with a diameter 225 m in laminar flow has been investigated in a microfluidic reactor. The periodic particle motion in a fluid was investigated under a sinusoidal magnetic field generated by a quadrupole arrangement of electromagnets around the reactor. The effect of operating frequency of the rotating magnetic field, intensity of the magnetic field, and phase shift between the two sets of magnets on particle dynamics has been studied. Three particle motion modes have been observed depending on the frequency of the applied field. The mass transfer rate was estimated under steady velocity and variable velocity of the particle using a mass transfer correlation by Feng and Michaelides (Int. J. Heat Mass Transfer 44 (2001) 4445). The validity of this correlation for the case of variable particle velocity has been confirmed with a 2D numerical model, describing actual hydrodynamics and mass transfer towards the particle surface. The mass transfer coefficient *Revised Manuscript (clean for typesetting) Click here to view linked References 2 depends both on the mean particle velocity and the deviation of velocity from the mean value.The periodic movement with variable particle velocity reduces the mass transfer coefficient by 7.6% as compared to steady state motion with the same mean velocity.
