摘要

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.
