求翻译：窄流道内的汽泡很容易生长至与流道相当的尺寸，其生长特性和运动特征均与常规流道相比不同。在实验工况下，借助高速摄像机，很易于观察到窄流道内汽泡沿着加热壁面滑移这一现象。但是由于技术受限，汽泡滑移运动对近壁面流动及传热的影响很难测量或表示。在陈德奇[1]等人对竖直窄流道内汽泡生长和脱离特性做的可视化实验基础之上，以商用软件 Fluent为平台，采用VOF两相流模型，数值模拟三维竖直窄流道内受限汽泡滑移对近壁区域流动和传热的影响。是什么意思？

Narrow flow inside the bubble is easily grown to the equivalent to the flow channel size, its growth characteristics and movement characteristics were compared with the conventional flow. In the experimental conditions, with high-speed cameras, it is easily observed in the narrow channel bubble slid

narrow stream of air bubbles in it is easy to grow with the stream, the size, with the growth and movement characteristics are compared to a regular runner. In lab conditions, with high-speed cameras, it is very easy to observe in the narrow channel along the heating vapor bubble wall slip this phen
