Thermo-Fluid Mechanic Study of Thermoacoustic Devices

Authors: A. Prosperetti; C. Herman; O. Knio; JOHNS HOPKINS UNIV BALTIMORE MD DEPT OF MECHANICAL ENGINEERING
Abstract:
The work summarized is divided into three parts. In Part I the development of a simplified model of thermo-acoustic devices is described and the results of its preliminary analysis documented. In Part II the results so far obtained in an experimental program designed for the visualization of flow and heat transfer in a thermoacoustic stack are described. Part III deals with the progress on a full Navier-Stokes numerical simulation of flow and heat transfer processes in the stack. Thermoacoustic, Refrigeration, Nonlinear waves, Nonlinear stability
