| dc.description.abstract | Industry have a many important operations and mixing of fluids is one of the most important industrial operations. Static mixers, also known as motionless mixers, are very efficient devices used for mixing of both single phase and multiphase fluids. Static mixer can actually be useful if an industry want to reduce the usage of conventional mixer and usage of static mixer are gradual increase in various industrial operations. Therefore, it is necessary to achieve higher mixing efficiency at the cost of minimum energy consumption. Mixing performance can be improved either by designing new internal geometry or by modifying an existing static mixer geometry. Static mixer parameter are also need to be study in order to understand more about static mixer. The objective of this research is to build a mathematical framework that represents mass transport in typical static mixers. In this simulation, the static mixer are open design with helices. The static mixer contain three elements (blades) and tube cylinder with certain diameter. COMSOL Multiphysics® 3.5 was used to examine the effect of different mean inlet velocity and diffusion coefficient on the mixing performance. It show that both parameter have different effect on the concentration of mixing. Another software was used, COMSOL Multiphysics® 5.4 used to study variation in the standard deviation of the particle in a static mixer. The result show that mixing performance of each parameter was compared based on dispersive mixing and distributive mixing parameters. For laminar flow regime and incompressible fluid, simulation results for all the static mixers are first characterized in terms of velocity field, which showed good agreement with the literature data. The mixing performance show better result with increase mean inlet velocity and the right amount of diffusion coefficient are needed in order to perform better mixing performance. | en_US |
