Abstract
In this paper, We measured the details of three-direction velocity components, U,V,W, fluctuating velocity u,v,w and turbulent shear stress -uv, -wv by means of the inclined hot-wire probe. The object of this paper is to examine the influence of these flow structure on heat transfer enhancement in a pipe. Moreover, shear stresses on the wall and local heat transfer coefficients were measured, and the non-analogy phenomena between the shear stresses and local heat transfer coefficients were discussed
