Interaction of Acoustic and Thermal Modes in the Gas with Nonequilibrium Chemical Reactions: Possibilities of Acoustic Cooling

Abstract

Nonlinear generation of thermal mode during propagation of dominative sound in a chemically reacting gas is considered. The dynamic equation of excess temperature associated with the thermal mode is derived. It is instantaneous and includes quadratic nonlinear acoustic source reflecting the nonlinear character of interaction between acoustic and non-acoustic types of gas motion. Both periodic and aperiodic sound may be considered in the role of origin of the thermal mode. An excess temperature associated with the thermal mode is negative in the nonequilibrium regime, if the standard attenuation is neglected. An example concerns to the heating (or cooling) caused by periodic sound. The role of standard viscosity, thermal conductivity, and heat withdrawal in a chemical reaction in producing of positive or negative excess temperature is discussed.
