Experimental and numerical investigation of inertial particles in underexpanded jets.

The article "Experimental and numerical investigation of inertial particles in underexpanded jets" delves into the behavior of inertial particles in underexpanded jets through experiments and simulations, focusing on their impact on shock structures and gas-phase dynamics. High-speed imaging and particle tracking were used to analyze flow characteristics, revealing complex interactions between particles and gas-phase flow. The study highlights the shift in Mach disk location towards the nozzle due to strong two-way coupling effects, with findings suggesting the need for improved models to handle such interactions in compressible flows containing solid particles.
