The study identifies the normal gradient of stream velocity as crucial for increasing viscous dissipation, thereby limiting outlet kinetic energy.
Results indicate that energy dissipation mechanisms are primarily linked to viscous properties of supercritical carbon dioxide, complicating flow behavior.
Numerical simulations of labyrinth channels were utilized to analyze fluid dynamics and thermodynamics in the context of pressure drop stability.
Findings provide essential metrics for assessing energy management in labyrinth regulating valves under high-pressure conditions.
