| Numerical study of the flow and residence time distribution of a microreactor with five parallel microchannels was considered. Three types were used in this work: type A, type B and type C. In type A and type C, trapezoidal structures were used for manifolds, while, in type B, the rectangular structure of manifold was used. The effect of manifold structure and the direction of inlet flow respect to the direction of the flow in microchannels were investigated on the residence time distribution. Along this considering, uniformity of flow distribution in microchannels was studied. Results show with increasing the velocity, the dimensionless variance increases. In the lower velocity, there isn’t a clear difference between type A and type C in the dimensionless variance value, but, with increasing the velocity, type C has lower dimensionless variance. So, flow in type C is more uniform than type A. while, the dimensionless variance for type B is less than type C. Also, in all types, type A, type B and type C, the tailing factor value is more than one, so, these types aren’t ideal model reactors. Based on another result, the channelization of flow was shown in the higher velocity. | ||
