  • The use of internal fins is a very effective means of augmenting heat transfer in a tubular heat exchanger, especially for the laminar flow case. Several theoretical investigations have been undertaken to determine heat transfer performance under fully developed conditions. Results reported in the literature are derived for prescribed thermal boundary conditions, wither with axially uniform heat flux with peripherally uniform temperature, or with constant temperature axially as well as circumferentially. However, for double pipe heat exchangers, the thermal boundary condition of the separating wall can not be prescribed a priori; it is determined by the thermal interaction between themore » fluid inside the tube and that in the annular space. Mikhailov and Shishedjiev (1981), and Tao (1986) have shown that Nusselt number of the tube and that of the annular are strongly dependent upon the heat capacity ratio of the two fluids. In this investigation, a performance analysis is conducted numerically for an internally finned tube which serves as the inner tube of a double pipe heat exchanger.« less
  • In this paper, results of an experimental investigation of mixed convection in laminar air flow across a tungsten wire are presented. Results are correlated by the 3-D surface equation of heat transfer, and compared with traditional equations for mixed convection which have been suggested by several investigators. Experimental results are given for Reynolds numbers in the range of 0.8 {le} Re {le} 17.5, Grashof numbers in the range of 1.5 {center dot} 10{sup {minus}3} {le} Gr {le} 25 and buoyancy parameter in the range of 6 {center dot} 10{sup {minus}5} {le} Gr/Re{sup 2} {le} 11.5.

  • The effects of tube geometry on the heat transfer and pressure drop characteristics of triangular-pitch tube banks containing smooth, integral, helicaily finned tubes with air draws by forced convection in cross flow through the banks were investigated. Heat transfer data are correlated and preseated graphically. (J.R.D.)
