Heat transfer in heat generating fluid with flat velocity profile and arbitrary fluid inlet and circumferential wall temperature distribution: Part II - ScienceDirectSolutions obtained in a previous article are developed in this paper for the case of cosinusoidal wall temperature distribution. Nusselt ...
Assumptions: The heat transfer occurring through the wall is considered one-dimensional. And the medium is isotropic with constant (uniform) thermal conductivity. Analysis: The temperature distribution within the wall in the x-direction is given, the heat equation for Cartesian coordinates can be used...
This paper deals with the problem of heat transfer in fully developed turbulent flow with uniform internal heat generation in a concentric annulus under conditions of uniform but different heat fluxes at the two wall surfaces. The Nusselt numbers at each wall surface are calculated by analyzing the...

Heat Transfer to a Fluid Flowing Turbulently in a Smooth Pipe with Walls at Constant Temperature. The case of heat transfer to an incompressible fluid of constant properties flowing turbulently within a pipe having constant wall temperature has been inv... RA Seban,T Shimazaki 被引量: 0发表:...
[15]. The effects of EHD on single-phase (liquid and gas) and two-phase (boiling and condensation) heat transfer systems on both horizontal and vertical surfaces were investigated. Léal et al. [3] worked on how heat and mass transfers between a fluid and a wall can be arisen using ...
The use of coiled square wire turbulators leads to a considerable increase in heat transfer and friction loss over those of a smooth wall tube. Introduction Heat exchangers have different applications ranging from conversion, recovery of thermal energy in different industrial, domestic and commercial ...
Subcooled flow boiling covers the region beginning from the location where the wall temperature exceeds the local liquid saturation temperature to the local where the thermodynamics quality reaches zero, corresponding to the saturated liquid state. Three locations in the subcooled flow have been identified...
