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.

Breath by Breath: Navigating the Landscape of Exhaled Breath in Clinical Research and Prospects for the Future

Journal of Analytical Methods in Chemistry, Volume 2026, Issue 1, 2026.
Exhaled breath analysis (EBA) has evolved as a noninvasive diagnostic technique with enormous promise in healthcare. The development in this area is based on the concept that the breathalyzers employed to measure the alcohol concentration in the blood can be utilized to evaluate health by analyzing the intricate chemical makeup of exhaled breath, which

Structural Stability of the Moore–Gibson–Thompson Heat Equation in a Semi‐Infinite Cylindrical Domain

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.
