Numerical calculation of a heat-driven thermoacoustic cooler with multiple pair of the cooler and engine cores (Study on cores where the cold side of the cooler and the ambient side of the engine are adjacent)

Journal of Fluid Science and Technology
Heat-driven thermoacoustic coolers (HDTACs) are promising technologies for reusing waste heat. Although numerous studies have been conducted on HDTACs, they have predominantly focused on small units at the laboratory scale, with limited work on larger ...

Exploring liquid fuel combustion dynamics in a swirl burner using dynamic mode decomposition

Engineering Applications of Computational Fluid Mechanics
Aero gas turbine engine combustors are transitioning from traditional Rich-Quench-Lean (RQL) staging to Lean Premixed Prevaporized (LPP) operation to reduce harmful NOx emissions and improve combustion efficiency.

Study on Coupling in a Thermoacoustic Driven Pulse Tube Refrigerator

Zhileng xuebao, 2018
Thermoacoustic-driven pulse tube refrigerators are usually coupled directly or by long tubes called acoustic amplifiers. With these coupling methods, the efficiency of the whole system is quite low because of the nonideal acoustic field and flow losses ...
