Pressure drop and cavitation investigations on static helical-grooved square, triangular and curved cavity liquid labyrinth seals

► Design and testing of newer and novel helical-grooved profiles of labyrinths capable of ensuring high pressure drops even at low liquid flow rates. ► Implementation of genetic algorithm in the optimization of labyrinth seal through surrogate modelling means. ► Application of CFD in three-dimensional fluid flow and cavitation analysis for static helical grooved labyrinth seals.
