Abstract

Computational fluid dynamics (CFD) model was developed using FLUENT 18.1to study the hydrodynamics in jet mixer for the prevention of sludge in a large storage tank containing crude oil. Eulerian approach was used to predict the flow behavior of sludge and k-e model also used to analyze the turbulence in the storage tank. The parameters such as velocity, time, nozzle head in single and time, nozzle head angle position in multi jet were analyzed. The velocity at 30ms -1 , the mixing pattern was appreciably good and the profile obtained was fully developed at the bottom. The profile developed in multi jet with various angle position also verified. RANS formulation for numerical analysis also verified in which the amount at all points were not exceeding 300 which was appreciable in modeling.
