| 摘 要： | 本文应用电子散斑干涉法(ESPI)和实时全息干涉法,从互相垂直的两个方向,同时测量了酒精灯火焰温度场和喷射(jet impingement)温度场。文中应用交互式高速数字图像处理系统处理了全息和散斑条纹图,并定量计算了剖面上的温度分布。还就可能出现的实验误差进行了分析。

| Abstract: | The temperature fields of alcohol flame and impinging jet are measured by simultaneously using ESPI and real-time holography in two orthogonal directions. An interactive high-speed image processing system is used to process the fringe patterns obtained by holography and ESPI. Temperature distributions of certain cross-sections are calculated quantitatively. Sources of error in the experiment are discussed. |
