Thermal mixing in T-shaped micromixers with a porous block by the lattice Boltzmann method: Influence of the mixing channel configuration

The present paper investigates the thermal mixing and cooling processes in a passive micromixer, which is applicable for of electronic devices. Employing porous block testing different configurations channel considered to enhance process performance. A 2D lattice Boltzmann model utilized investigate performance T-micromixer with block. Two types configurations, including step-shaped zigzag-shaped channel, are considered, obtained results compared those simple channel. two miscible fluids, at 50 25°C entering investigated. show that changing configuration may create chaotic laminar flow, enhances heat transfer rate between mixed flow wall. Whatever Reynolds number, exhibits better than one. For cases h/H = 0.5 0, respectively, exhibit
