COMPUTATIONAL STUDY OF NATURAL CONVECTION THERMAL RADIATION HEAT TRANSFER IN TIGHTLY COILED CURVED PIPE FOR SMALL RANGE OF PECLET NUMBER
要約
Natural convection heat transfer in a tightly coiled curved pipe is studied using the Navier−Stokes equation in cylindrical coordinates system. Transverse and axial components of flow field, temperature field, heat transfer rate, transverse and axial components of skin friction are examined. The proposed model is solved for different ranges of curvature of the pipe δ angle α, radiation parameter Rd, and Peclet number Pe. In this study, the nonlinear differential equations are transformed into convenient form by using a group of transformations and then solved by using the finite difference scheme. Useful correlations are proposed graphically for the different ranges of parameters involved in the present problem.
