A SEMI-EMPIRICAL DERIVATION OF FRICTION, HEAT-TRANSFER, AND MASS-TRANSFER COEFFICIENTS FOR THE CONSTANT PROPERTY TURBULENT BOUNDARY LAYER ON A FLAT PLATE

Abstract

The friction coefficient and velocity profile are calculated from the relation between the shear, the sum of the molecular and eddy viscosity, and the velocity gradient. The non-dimensional shear distribution is assumed to be fixed. The eddy viscosity across the boundary layer is obtained by joining a distribution for the wall region to one for the outer region. By use of the shear and eddy viscosity distributions the velocity profile is calculated from the wall to the outer edge of the boundary layer for all Reynolds numbers without using the concept of laminar sublayer, transition region, logarithmic region, etc. The heat and mass transfer coefficients and the temperature and concentration profiles are calculated by a similar method.
