dc.description.abstractConvective heat transfer coefficient is strongly influenced by the mechanism of flow during forced convection. In this paper, the effect of pipe roughness on friction factor and convective heat transfer in fully developed turbulent flow are briefly discussed. A correlation for the friction factor applicable in the region of transition to the fully developed turbulent flow regime is proposed. Using this relationship, some new approximation formulae are proposed to predict the convective heat transfer coefficients in the pipes with a relative roughness of epsilon/D less than or equal to 0.05. The effectiveness parameter. for the heat transfer is investigated as a function of the pipe roughness, Reynolds number and Prandtl number. The effect of fouling is also briefly discussed. The: predictions of the proposed correlations are compared with the experimental data and with some other previous correlations given in the literature. (C) 2002 Elsevier Science Ltd.
