LAW OF THE WALL AND VELOCITY DEFECT LAW IN FULLY TURBULENT NON-BAFFLED AGITATED VESSEL

[摘要] References(7)Cited-By(7)The characteristic friction velocity in an agitated vessel is defined, based on the assumption that the flow field is affected by the condition at impeller tip. The velocity profiles are well correlated in terms of the dimensionless variables defined by using this friction velocity. The correlation equations are given for the wall vicinity, potential and impeller regions, respectively. Two of them may be regarded as law of the wall and velocity defect law in agitated vessels.
