The paper deals with the analysis of the influence of the groove axial length, number and position on the total side thrust acting on a spool inserted into a tapered clearance. Adopting a numerical approach based on the Reynolds equation property combined with the continuity equation, the hydraulic locking phenomena are studied for different tapered clearances of practical interest in the presence of different groove configurations. The variation in groove axial length, number and axial position makes it possible to collect important information about the multigrooved spool in a thin film of fluid, including fundamental data for a proper spool design.

Abstract
The paper deals with the analysis of the influence of the groove axial length, number and position on the total side thrust acting on a spool inserted into a tapered clearance. Adopting a numerical approach based on the Reynolds equation property combined with the continuity equation, the hydraulic locking phenomena are studied for different tapered clearances of practical interest in the presence of different groove configurations. The variation in groove axial length, number and axial position makes it possible to collect important information about the multigrooved spool in a thin film of fluid, including fundamental data for a proper spool design.
