Book Description
Turbulent combustion remains a very active research area. This interest is justified due to the pivotal role it plays in a wide variety of technologically important processes. Development of models for combusting flows is crucial for the more efficient utilization of limited hydrocarbon fuel resources, reduction in environmentally harmful pollutants, more efficient chemical processes, and for the prediction of hazard associated with unwanted fire. An important subset of turbulent combustion is turbulent jet diffusion flames because they are relatively simple to generate, and because they provide an appropriate testbed for the development of more general theories for turbulent combustion.

Book Description
This work describes the development and characterization of an experimental system employing laser-induced Rayleigh light scattering with digital data acquisition as a time-resolved, quantitative concentration probe in the turbulent flow field of a binary gas mixture. Equations for the expected signal and noise levels are given. Estimates of these parameters for the experimental system used here are in satisfactory agreement with experiment. It is demonstrated the laser Rayleigh light scattering technique does provide highly spatially- and time-resolved measurements within the concentration flow field. Measurements at various postions in the flow field of an axisymmetric methane jet issuing into a slow flow of air are reported and where possible, compared with appropriate literature results. The statistical properties of the turbulent concentration fluctuations are found to be in good agreement with other independent measurements. Conditionally sampled measurements are also reported and shown to behave in the same manner as the limited number of similar measurements in the literature. The capability of calculating power spectra and correlation functions for the time behavior of the methane concentration is also demonstrated. Other techniques employed for scalar measurements in turbulent flow fields are briefly re-viewed and the utility of these techniques for measurements in different types of flow systems are discussed in relation to the Rayleigh light scattering method.

Book Description
This volume contains most of the papers presented at the "Workshop on Quasielastic Light Scattering Studies of Fluids and Macromolecular Solutions" held at CISE, Segrate (Milano), Italy, from 11 to 13 May, 1979. Quasielastic light scattering (also called self-beating spectroscopy or intensity correlation spectroscopy) is the technique, introduced by Benedek and coworkers and by Cummins and coworkers about 15 years ago, by which dynamical information about a scattering medium is obtained through the measurement of the power spectrum (or the intensity correlation function) of the laser light scattered from the medium. The technique received in the early seventies a considerable impulse from the development of real-time fast digital correlators. The aim of the Workshop was to bring together a selected number of researchers in order to discuss recent developments in quasielastic light scattering and related optical methods and to report about new applications of the technique in physics, chemistry and biology. The first two days of the meeting were devoted to the oral presentations of papers. In the third day an informal session was held which included a very lively and thorough discussion of the highlights of the Workshop. Most part of the technical problems were debated during the informal session and during the subsequent visits to the light scattering laboratory in CISE.
