Mixing and Agitation of Fluids - mintecco

2013-12-23  The flow mechanism in a mixing tank is very complex. Varioustechniques, including computational fluid dynamics (CFD) and compu-tational fluid mixing (CFM) tools, are employed together with experi-mental data to establish improvements in mixing with increased yield.Estimating the power consumption for any agitator is essential fordesign. Generally, the desired requirements for the system to be mixedwill categorize the type of impeller to be used. Laboratory tests onthe system can establish the appropriate speed for the maintenance ofisotropic turbulence in the mixing vessel. Therefore, estimating thepower consumption for a large-scale mixing operation must includescale-up considerations. These requirements may be determined fromthe Navier-Stokes equation or analyzed by a dimensional analysis ofthe mixing
