“…Fundamentals of physical principles underlying the regenerator were investigated and analyzed in previous papers, [6,7] while the regenerator's parameters were optimized by several researchers. [7][8][9][10][11][12] Swift [7] studied the hydraulic radius r h in the thermoacoustic system and obtained the empirical values: r h /δ k ∼ 1 for standing wave engine and r h /δ k 1 for traveling wave engine, where δ k is the thermal penetration depth. Tijani [8] studied a standing wave thermoacoustic cooler and put forward that r h = 1.25δ k was optimal for the cooling power, r h = 2.0δ k led to the lowest temperature, and the highest efficiency could be reached when r h = 1.5δ k .…”

“…Tijani [11] experimentally investigated the effect of Prandtl number on the performance of a thermoacoustic refrigerator using gas mixtures. Kazuto [12] considered correlations of the local Nusselt number distribution and analyzed heat transfer characteristics of the oscillatory flow in the engine core via numerical simulations.…”
