Track: Modeling and Simulation

Abstract

The mixing of different chemicals has traditionally been achieved using a rotating paddle in a tank. An alternate option to mix chemicals together is using jet nozzles to spray them into the tank. This paper presents different setups that could be potentially used for selected tank and find the optimal design. The aspects that are changed in the report where the inlet pipe location, the outlet pipe location and the inlet fluid speed. By using SolidWorks to create the models and Star CCM+ to run the simulations, the results of each test where generated and analysed. The validation had been conducted prior to the simulation. When analysing the results, the primary area of interest was the location and size of any dead zones that occurred in the tank during the running of the simulation. The results show that the optimal design for this tank is a side entry inlet pipe at the top of the tank with a side exit outlet pipe at the bottom of the tank, perpendicular to the inlet pipe. It was also shown that a slower inlet speed improved the quality of the mixing process.
