The author proposes here a new vorticity transfer theory whose fundamental form is γ.B.=-ζ/2D<lα^2υ'>^^^-d^2-u/dy^2 where γ.B. is Reynolds stress, l the mixture length, α^2d^2u/dy^2 the circulation arround turbulent fluid particle and D the distance between the particle and its image refered to wall surface. Effect of viscosity is introduced as a loss of vorticity which appears in the expression of ν'. As an application of the theory the flows through circular pipe are calculated, and the result shows a good coincidence with experiment especially in the neighbourhood of wall. The theory can also explain the reason for variation of coefficient of correlation.
