Analysis of Mixing Effectiveness of Perforated Plate for Inline Static Mixer

Abstract

Inline static mixer can be used in a wide range with a different application such as mixing liquids, chemical processing and biodiesel blending. Currently, an issue in producing more effective static mixer for mixing liquids by introducing circle grids fractal plate drew the attention of the researchers. Therefore, this research is focusing on implementing a circle fractal plate as a mixing element for inline static mixer to increase a mixing effectiveness. Furthermore, it was assumed that the new type of circle grids fractal is simple to install and easy to manufacture. Besides that, pressure drop shows a significant effect in producing a better static mixer. This study will have conducted experimentally to analyze the effect of pressure drop on mixing effectiveness by using different perforated plate with different porosity which are NEL plate with 47.5% porosity, fractal perforated plate, 51.85% porosity and unchamfered plate, 62.85% porosity. For data collection, pressure value at upstream and downstream are recorded for analysis with different six openings of the discharge ball valve. The results shoes that the unchamfered plate produced higher mixing effectiveness. This statement was strengthened by the images of flow visualization and pressure drops table gained from the experiment. This finding can be useful for a future economic static mixer with the best performance for industrial needs.
