Abstract

Variations of mean velocities, turbulence intensities, time scales, and spatial scales of turbulence in an engine cylinder during the compression stroke are investigated in detail. Single sensor hot-wire probes of different shapes are used to measure the three orthogonal components of the velocity, and spatial scales of turbulence are determined from the cross-correlation coefficients of turbulence. A new model for fine structure of isotropic turbulence is proposed.
