Abstract
Micromixers are important modules in medical applications. Novel and excellent biometric micromixers have been designed with an effective mechanism of flow splitting and recombining (SAR). The aim of this study is to modify the prototype of a biometric micromixer by designing the inlet flow channel and generating a better flow geometry in the blood vessel-micromixer. The blood vessel-micromixer was also investigated with different inlet channel angles and various Reynolds number ratios (Re-12 and Re-r) for the estimation of their influence on the mixing performance of the micro-mixer. The Re-1(2) is the inlet 2 and the Re-r is the combination of side flow and middle flow effects during the different flow conditions. Results showed that the blood vessel-micromixer with an inlet channel angle of 30 degrees (circle divide =30 degrees) can be optimized for future research works. In addition, optimal performance with a Amixing index of 0.88 would be achieved at a condition of Re-12= 1 and Re-r = 0.7. These findings will be definitely useful for the improvement of micromixer applications in the future.
