✦ Synopsis

We model a single-plate thermoacoustic system under the action of a transverse magnetic force. Simplified momentum and energy equations are solved, in the frequency domain, in order to obtain the expressions of the fluctuating velocity (u 1 ) and temperature (T 1 ). Time averaged and space averaged heat fluxes and work fluxes are calculated. The effects of the drive ratio (DR), Hartmann number (Ha d ), temperature gradient (jT m ), and frequency ( f ) on the heat flux, work flux, and operating conditions are discussed and graphically presented.
