Short description and remarks

'Mixing of Single and Multiphase fluids in Stirred Tank Reactors is a very common operation in many chemical industries.Understanding the fluid flow in these tanks is critical for equipment design, scale-up,process control and many economic factors.Modelling the fluid flow allows us to see what is taking place in the mixing vessel.The results enable an Engineer to select the best Agitator Designs to obtain the desired mixing performance.
This page contains the 2D simulation of fluid flows in a circle of 14.5 units with four circles of radius 1 unit, located from the centre at a distance of 3.7 units.The Agitator blades consists of 4 squares of dimension 2.25 * 0.56 units The calculation starts from rest. The flow is observed with the Reynolds no 100000 This simulation is part of a Software-Praktikum at the University of Dortmund in 2004.
