Evaluation of the Intensity of Turbulent Velocities by Using a Cross-Correlation Technique for Pattern Tracking 960267
This paper reports the development of a method for evaluating the intensity of turbulent velocities by using a cross-correlation technique for pattern tracking. With this method, only a pair of flow field images having a short time interval between them is required to perform the evaluation. The method is verified partially by its ability, when it is simplified, to reveal several phenomena observed previously in the velocity measurement by the cross-correlation technique for pattern tracking. An application to the estimation of turbulent intensity in a diesel engine combustion chamber after combustion is described.
