Evaluation of Cycle-Resolved Filtering Analysis Techniques for Estimating Turbulence Parameters from In-Cylinder LDA Velocity Measurements,

Abstract : Cycle-resolved filtering analysis techniques have been used extensively for estimating turbulence parameters from in-cylinder velocity measurements. In this paper the performance of such filtering techniques in separating velocity fluctuation components is investigated systematically by analysing simulated data. This data exhibits all the characteristic features of real engine data, with a range of statistical properties covering all those estimated in previous studies. (Author)
