Sažetak
A thorough knowledge of hydrodynamic conditions of the liquid-liquid flow in a microreactor is necessary for performing multiphase reactions. In this work the liquid-liquid flow profile in a microreactor was investigated. Different organic solvents (dichloromethane, diethyl ether, chloroform and toluene) as one phase and water as second phase were fed in a microreactor. Two microreactors with internal volume of V = 4 mm3 and V = 6 mm3 with different microchannel surface roughness were used to analyzed the effect of surface roughness on flow profile. The flow profiles in the microchannel were monitored under the microscope. The analysis of specific dimensionless numbers (Reynolds number, Capillary number and Weber number) was performed to get the better insight in process dominant for specific flow profile formation.
