TEHL Analysis of Rough Surface Spur Gears with Non-Newtonian Lubricants under Sudden Overloads
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 The time-dependent modified Reynolds equation, elasticity equation, and energy equation with initial conditions were formulated and solved numerically using a multi-grid multilevel with full approximation technique for an involute spur gear.

Thermo-mechanical response of TEHL contacts under dynamic loading conditions
Tribology InternationalA CFD-FSI approach is employed to investigate the thermo-mechanical response of TEHL contacts to time- varying loading conditions. The response to an impact load, with increment Delta f over time Delta t, and taking into account the equivalent system mass m, on film thickness, pressure and temperature variations, is being investigated.

Effect of fluid inertia force on thermal elastohydrodynamic lubrication of elliptic contact
Mechanics & Industry, 2021 A non-Newtonian thermal elastohydrodynamic lubrication (TEHL) model for the elliptic contact is established, into which the inertia forces of the lubricant is incorporated.

Transient mixed lubrication model of the human knee implant
Biosurface and Biotribology, Volume 7, Issue 4, Page 206-218, December 2021., 2021 Abstract The human knee implant is computationally modelled in the mixed lubrication regime to investigate the tribological performance of the implant. This model includes the complex geometry of the implant components, unlike elliptical contact models that approximate this geometry.
