布置错位通道的微混合器内流体热混合特性

基于常规平面微混合器内流体混合特性的研究，对布置错位通道的微混合器进行了三维数值模拟，分析了指定Reynolds数范围内微通道内流体的热混合特性。计算模型采用有限体积法离散、SIMPLEC算法进行层流计算。结果表明，温度在指定范围变化时，其对混合性能的扰动作用较小。此外，由于错位通道结构所产生的漩涡在促进混合的同时降低了流体工质的温度。

Thermal Mixing Performance of Micromixer with Dislocation Sub channel

Based on the mixing performance analysis of fluids in the passive micromixer, the thermal mixing performance of T shaped micromixer with dislocation sub channel has been analyzed numerically with three dimensional Navier Stokes equations under particular range of Reynolds numbers in this paper. The finite volume method is used to disperse the three dimensional steady incompressible N S equations. The result shows that the temperature has a small role in the disturbance of the mixed performance when it is changed within a specified range. Furthermore, the vortex generated by the dislocation sub channel structure facilitates mixing as well as reduces the temperature of the working fluid.
