Article Synopsis
- The study investigates a 3D simulation of magnetorheological (MR) conical bearings, focusing on viscous dissipation and using a conjugated heat transfer approach.
- The behavior of MR fluids is modeled using the Bingham-Papanastasiou equation, considering how viscosity and yield stress change with magnetic field intensity and temperature.
- The research employs a multidisciplinary approach with fluid dynamics, magnetism, and heat transfer, using finite element methods to solve governing equations, and highlights the significant impact of temperature on the performance of MR conical bearings.
Article Synopsis
- This paper introduces a new analytical solution for understanding how viscoelastic lubrication works in journal bearings using the perturbation method.
- It utilizes the nonlinear Giesekus model to analyze factors like fluid elasticity, shear-thinning behavior, and strain-hardening effects on lubrication performance.
- The findings reveal that increased fluid elasticity significantly boosts load capacity in bearings, showing different behaviors in linear and exponential regions related to characteristic parameters like mobility factor and Weissenberg number.
