Mixing characterization and energetic dissipation in different networks of minichannels

摘要: Abstract This work is dedicated to the mixing characterization inside two geometries of minireactor by using an electrochemical method. The first one composed only minichannels crossing at right angles while second includes and T_shaped parts. used method consists measure limiting diffusion current surface microelectrodes flush-mounted into wall 10 outlet each network. linked concentration electroactive species flowing in its measurement allows cell radial dispersion tracer injected middle upstream part effectiveness characterized for Reynolds number ranging between 55 250 comparing response on microprobes located channel. experimental results show distinctly that geometry more promising terms process than network minichannels. Pressure drop measurements are carried out numbers from 1 1000 order evaluate energetic dissipation. data show, both cells, pressure loss can be represented a Reynolds–Forchheimer-type equation characteristic porous media.
