摘要：In this study,a numerical model for axial heat conduction effects in laminar circular tube flows has been developed using the finite difference method.The calculations have been done using different Peclet numbers in the range of 0.5 to 100.Constant heat flux and constant wall temperature boundary conditions have been used.The validity of the numerical model has been checked by some data in the literature.The results were presented for temperature variation,Nusselt number,and energy absorbed before the heated section.The axial conduction effects may be important for micro tubes,which are to be used in micro heat exchangers.
