Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
Single -phase flow field and temperature distribution
in a baffled tank stirred by a three- bladed impeller was
investigated both computationally and experimentally.
The computational model employed a sliding mesh
technique in fully three-dimensional grids for a smallscale
unit, in which also velocity and heat transfer
measurements were made with water. Turbulence
effects were simulated using the standard k-ε model.
Two different boundary conditions, namely, constant
heat flux and constant temperature on the wall were
used for heat transfer simulations. Mean velocity and
turbulence were measured using LDA. In temperature
measurements thermocouples were used. By
comparing experimental and modelled results nondimensional
variables of velocity were found, which
gave very similar results to the pilot unit and full- size
reactor of 12 m3, for which some modelled heat transfer
results are given.
