摘　　要：在间隙分别为2.0mm和1.5mm的垂直环形窄缝通道内,流体自下而上流动。本文通过对内外管的双面通电加热来加热流体,进行环形窄缝通道内干涸点测定的实验研究。实验压力范围为2～4MPa,质量流速为40～80kg·m-2·s-1。采用原苏联古塔杰拉奇普通圆管的干涸点公式的形式对实验数据进行处理,得到了经验关系式,并对其进行修正,得到了适合于计算环形管道干涸点的经验关系式。This paper presented an experimental study of the dry-out point of flow boiling in bilaterally heated narrow annular channel with 1.5 mm and 2 mm annular gap, respectively. The range of pressure is 2.0-4.0 MPa and that of mass flux is 40-80 kg/m2. s. Kytatkliaze's equation which was adaptable to tubes was used to deal with the experimental data and an empirical equation was obtained. Again this empirical equation was amended, then an empirical equation of the dry-out point suitable for narrow annular channel was obtained.
