VisiMix Turbulent for mathematical modeling of turbulent mixing in reactor with 2-stage Lightnin impeller.

Problem description:

You will obtain some general data on your mixing equipment, which will enable you to evaluate the general suitability of your equipment, compare different designs, etc. These parameters are used as basic data for calculations of other mixing problems.

Initial data

Tank Flat bottom:

  • Inside diameter = 3000 mm
  • Total volume = 35 cub.m
  • Volume of media = 30 cub.m

Baffle (Flat, attached to the tank wall):

  • Number = 4
  • Width = 300 mm;
  • Length = 4200 mm;
  • Distance from bottom = 0 mm.
  • Angle to radius = 0 deg.

Impeller:

  • 2-stage Lightnin A310
  • Tip diameter = 1300 mm
  • Distance between stages = 2000 mm
  • Distance from bottom = 375 mm.
  • Rotational speed = 80 rpm
  • Power of drive = 10 kW

Media properties:

  • Type of media = Newtonian
  • Density = 1100 kg/cub. m
  • Dynamic viscosity = 4.5 cP
