✦ Synopsis

An integral equation, which is based on the free space Green function approach, is presented for the analysis of sound radiation from a vibrating surface into a viscous fluid by taking into account the small entropy fluctuations inherent in the process. The thin acoustic boundary layer approximation has been made in determining fluid vorticity and heat flux in the close vicinity of solid boundaries. Numerical examples have been given to show the visco-thermal effects on sound radiated from a vibrating surface and also the non-uniqueness problem.
