摘要

摘要: 基于经典的瞬态热线法原理,设计研制了一种适用于高温高压条件下测量多组分碳氢燃料导热系数的实验装置.对无水乙醇、甲苯及高压氮气进行了标定,结果表明液相导热系数最大偏差在1%以内,气相导热系数最大偏差在3%以内.进而对国产碳氢燃料RP-3导热系数进行了测定,温度范围298~430 K,压力范围0.1~5 MPa.改进和完善了超临界压力下流体导热系数的测量方法.

Abstract: Based on the classic trasient hot-wire princeple, the experiment apparatus for the measurement of multicomponent hydrocarbon fuel thermal conductivity under high temperature and high pressure was introduced. The calibration results of absolute ethyl alcohol, toluene and high pressure nitrogen show that the maxmum deviation for liquid thermal conductivity is less than 1% and for gas is less than 3%. After that, conductivity of domestic hydrocarbon fuel RP-3 was measured under 298~430 K and 0.1~5 MPa using this apparatus and the results show a good repeatibility. It is of great importance to improve conductivity measuring mehtods for fluid under super-critical pressure.
