What is Grooved Annular Seal Friction Model about?

This paper presents a lubrication film friction model specifically for grooved annular seals, which are crucial in turbomachinery design. The authors explore a friction factor model and a calibration method through extensive RANS simulations and experimental validation, demonstrating good predictions for pressure differences, although force predictions showed some deviation. The findings enhance the understanding of grooved seal behavior and improve the applicability of existing lubrication models.
