Two-dimensional numerical simulations of nonlinear acoustic streaming in standing waves [PDF]
Numerical simulations of compressible Navier–Stokes equations in closed two-dimensional channels are performed. A plane standing wave is excited inside the channel and the associated acoustic streaming is investigated for high intensity waves, in the ...

This paper describes a numerical model based on discontinuous Galerkin method for thermoacoustic investigation. Numerical investigation was conducted to study the behaviour of thermoacoustic wave propagations induced by thermal effects in 2‐dimensional enclosure. The compressible Navier‐Stokes equations are used as the governing equations.

Thermodynamics Performance Analysis of Solar Stirling Engines
This paper provides numerical simulation and thermodynamic analysis of SOLO 161 Solar Stirling engine. Some imperfect working conditions, pistons′ dead volumes, and work losses are considered in the simulation process. Considering an imperfect regeneration, an isothermal model is developed to calculate heat transfer.

Traveling-Wave Thermoacoustic Refrigerator
A new type of speaker-driven thermoacoustic refrigerator is described. By the measurement of the acoustic field formed in the refrigerator, it is shown that the refrigerator uses a traveling-acoustic wave for heat pumping through ideally reversible heat transfer. It is also shown that the efficiency of the refrigerator is improved by the suppression of

Heat transfer processes in parallel-plate heat exchangers of thermoacoustic devices - Numerical and experimental approaches [PDF]
This paper addresses the issues of heat transfer in oscillatory flow conditions, which are typically found in thermoacoustic devices. The analysis presented concerns processes taking place in the individual "channels" of the parallel-plate heat ...
