Abstract

The application of digital interferometric techniques in the measurement of forced convection in compact channels is examined. Michelson Interferometry and Mach–Zehnder Interferometry have been compared and contrasted, in terms of the suitability for temperature measurements. A wedge-fringe setting parallel to the heated surface has been utilized as the basis of the fringe analysis, for effective measurement in small dimension channels. Michelson interferometry was found to provide a larger number of data points in the visualization field, thus proving to be a better method of measurement in compact passages. Heat transfer parameters, useful in heat sink design, were also calculated.

紧凑通道中强制对流场的数字干涉测量

研究了数字干涉测量技术在紧凑通道强制对流测量中的应用。迈克尔逊干涉法和马赫-曾德干涉法在温度测量的适用性方面进行了比较和对比。平行于受热表面的楔形条纹设置被用作条纹分析的基础，以便在小尺寸通道中进行有效测量。迈克尔逊干涉测量法在可视化领域提供了大量的数据点，因此证明是一种更好的紧凑通道测量方法。计算了散热器设计的传热参数。
