Digital Image Analysis of Two Phase Flow Data.

Abstract

The analysis of flow visualization data documenting a variety of fluid phenomena has been severly limited in the past by the subjective nature of data interpretation and limitations imposed by actual sample size. Video digitization offers a reliable method of automating the analysis of such visual data. This paper describes an experiment wherein the distribution of sizes of bubbles formed by air injection into a water stream was found. Previous results were limited to special cases due to the amount of data required for a full documentation. Several geometric and flow parameters were varied and their effects are reported. Data reduction was via a digital image processing system. This type of system holds the promise of high speed, objective data reduction for a broad range of fluid mechanics problems. (Author)
