“…Oil pressure support normal load in conjunction with rough contact, form a type of hybrid friction. With normal pressure increased, the interface deformed to endure more normal pressure [5]. Both viscous cutting and rough contact generated much heat which result in oil viscosity decreased and intensify squeezed film process.…”

“…Then a single-phase flow CFD model with grooved clutch was established by Aphale et al (2010), which stated that grooves is beneficial for the escape of oil. Also, a simulated model established by STAR-CCM and experiments on the relationship between flow rate and drag torque were conducted by Madhavan et al (2012). Similarly as a kind of open source software, OpenFOAM was used by Takagi et al (2012), to simulate the hydrodynamic process of drag torque of wet clutch with the radial and circumferential groove geometry taken into account.…”

Purpose The purpose of this paper is to reduce the drag loss and study the effects of operating conditions and groove parameters such as flow rate and temperature of automatic transmission fluid, clearance between plates, groove depth and groove ratio on the drag torque of a wet clutch for vehicles, parametric analysis of the drag torque model of wet multi-plate friction clutch with groove consideration. Design/methodology/approach Both experimental and numerical research was carried out in this work. Parametric groove models, full film lubrication flow model and pressure distribution model are established to investigate the effects of the grooves on drag torque of a wet clutch. Multigrid method is used to simplify the solution. Findings In this paper, a drag torque model of a wet multi-plate friction clutch based on the basic theory of viscous fluid dynamics is examined through experimental and numerical methods that take grooves into account, and the change trend of drag torque with operating conditions and groove parameters is analyzed. Originality/value Multigrid method is used to solve the governing equations, which simplifies the solution process because of the restrictions and interpolation operations between the adjacent layers of coarser and fine grids. These works provide insight into the effect regularity of operating conditions and groove parameters on drag torque of a wet multi-plate friction clutch. Furthermore, variable test conditions and sufficient experimental data are the main functions in the experimental research.
