Abstract
MICROREACTOR TECHNOLOGY GAINED ON ITS MOMENTUM THROUGH DEVELOPMENT OF DEDICATED MICROMANUFACTURING TECHNOLOGIES. ONE OF THE CRUCIAL COMPONENTS OF A MICROREACTOR IS A MICROMIXER. ITS FUNCTION IS TO MIX DIFFERENT REACTATNTS FOR THE PURPOSE OF CHEMICAL SYNTHESIS OR ANALYSIS. IN THIS PAPER TWO ESTABLISHED MICROMIXER DESIGNS, NAMELY OBSTACLE AND MODIFIED TESLA MICROMIXER, ARE NUMERICALLY INVESTIGATED AT REYNOLDS NUMBER OF 0.5. POSSIBLE SYNERGIES OF INCORPORATING BOTH GEOMETRIES IN A SINGLE DESIGN WERE ALSO INVESTIGATED. THE SIMULATIONS SHOW THAT OBSTACLE DESIGN BY ITSELF PERFOR MS THE BEST IN RAGARDS TO MIXING INDEX AND PRESSURE DROP. ON THE OTHER HAND COMBINED DESIGNS PERFORMED BETTER THAN MODIFIED TESLA DESIGN BY ITSELF. WE CONCLUDE THAT FURTHER STUDIES ON OBSTACLES LAYOUT WITHIN THE MODIFIED TESLA DESIGN ARE SENSIBLE IN ORDER TO FULLY EXPLOIT THE MIXING PRINCIPLES OF BOTH DESIGNS.
