Description Micro-reactor are reactors with three dimensional structures, the inner dimensions of which are under a millimeter in size. Micro-structured reactors can be advantageously used as process engineering tools for acquiring information which allow in a short time and with greater safety, a process to be transferred to the pilot and production scale. Information for micro-structured reactors can also be used for optimizing process plats already in operation. Micro-structured reactors are suitable for the exothermic/endothermic reaction and or limited by mass transfer.
The objects of the experiment are to study phenomenon of bubble velocity for gas-liquid flow as Taylor flow at 2 conditions of which are first constant-volumetric flow rate of gas 0,75 ml/min and volumetric flow rate of ethanol varies between 0,2 ml/min-1 ml/min, and second for constant-volumetric flow rate of ethanol 0,3ml/min and volumetric flow rate of gas varies between 0,3 ml/min- 1 ml/min.
Two configuration of reactors(canal take form "t": canal take from serpent/meander) are used in this experiment. Results of experiment show the the bubble velocity has fluctuated to time with certain period amplitude. Bubble velocities are proportional inverse to dimension of bubble.
