研究了高温气体在受限混合空间内横向流动时空心锥喷雾蒸发混合过程的传热特性。研究在横截面积为95×95 mm的矩形管道中进行。使用热电偶测量了横流的四个横截面（半个横截面上的45个测量点）上的温度。获得了空心锥喷雾蒸发过程中气体横流的温度场，研究了横流速度、横流温度、喷雾液滴尺寸和喷雾喷射角等因素对温度场的影响。主要研究结果如下：1）多分散的空心锥喷雾液滴和液滴与壁面的碰撞使得流场横截面上的传热具有固有的不均匀性。2)混合流场分为五个区域，其特征在于不同的传热机制。3)交叉流的温度分布。
This work focused on the heat transfer of the mixing process resulting from a hollow-cone spray evaporation in high-temperature gas crossflow in a confined mixing space. The study was carried out in a rectangular duct with a cross-sectional area of 95×95 mm. The temperatures on four cross sections (45 measuring points on half of a cross section) of crossflow were measured using thermocouples. The temperature pattern of gas crossflow caused by the evaporation of hollow-cone spray was obtained, and the effects of factors such as crossflow velocity, crossflow temperature, spray droplet size, and spray injection angle on the temperature pattern were investigated. The main findings of this study were as follows: 1) The polydispersed hollow-cone spray droplets and the droplet-wall impingement made the heat transfer on the cross section of the flowfield inherently nonuniform. 2) The mixing flowfield fell into five regions characterized by different heat transfer mechanisms. 3) The temperature pattern of crossfl...
