Good Agreement

The problem considered is the determination of the heat transfer in fully developed turbulent flow of a radiating optically thin gas in a circular tube. The radiation problem is formulated in terms of the Planck mean and the modified Planck mean coefficients and the temperature profiles and Nusselt numbers have been determined. It is shown that the simple constant shear, constant heat flux formulation yields results that are in very good agreement with more complex calculations.

Effect Of Surface

Experiments are performed to study the effect of surface coke deposition on heat transfer of aviation hydrocarbon RP-3 under supercritical pressure. The flowing RP-3 kerosene is stressed to 5MPa, and heated up to 130°C to 450°C in a stainless tube (1.8mm I.D., 2.2mm O.D., 1Cr18Ni9Ti) with a constant heat flux, and the mass flow rate is 3g/s. The working fluids flowed downwards through an 1800mm long tube. The experimental results indicated that insoluble products deposited onto metal surface have a significant impact on flow resistance and heat transfer the effect of coke deposition on heat transfer coefficient can be divided into four regimes: a) onset heat transfer enhancement zone; b) transition zone; c) heat transfer impairment zone; d) heat transfer stabilizing zone.
