An Experimental PIV/POD Study on the Sequentially Coupled Flow Field of Swirl and Multiple Jets
International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.The stepwise flow reconstruction induced by sequential coupling of swirl, primary jets, and dilution jets was experimentally investigated in a model combustor using high‐speed PIV and proper orthogonal decomposition (POD). Three nonreacting configurations were compared: pure swirl, swirl plus primary jets, and swirl with both primary and dilution jets.

Study of a thermoacoustic-Stirling engine [PDF]
The Journal of the Acoustical Society of America, 2008 During the last decade most efforts in thermoacoustics have been focused on the development and understanding of the traveling-wave thermoacoustic systems. These systems get much attention because they employ the inherently efficient Stirling cycle.

Journal of Mathematics, Volume 2026, Issue 1, 2026.This work analyzes the continuous dependence of solutions to the Moore–Gibson–Thompson (MGT) equation formulated via Green–Naghdi Type III second gradient elasticity theory. The governing system is defined on a semi‐infinite cylindrical domain, subject to homogeneous Dirichlet conditions on the lateral boundary.
