  abstract     = {{The film thickness, lubricant temperature, and traction curves of two groups of commonly used constitutive models for lubricants in Thermo-Elastohydrodynamic Lubrication (TEHL) modeling were compared in this study. The first group comprised the Tait equation of state, the Doolittle Newtonian viscosity model, and the Carreau shear thinning model, while the second group included the Dowson equation of state, the Roelands–Houpert Newtonian viscosity model, and the Eyring shear thinning model. Simulations were conducted using a Computational Fluid Dynamic and Fluid-Structure Interaction (CFD-FSI) approach and conducted under a load range of 100 kN/m to 200 kN/m and a slide-to-roll-ratio (SRR) range between 0 and 2 using Squalane lubricant. Up to a 10% deviation in central film thickness, a 31% deviation in coefficient of friction (CoF), and a 38% deviation in maximum lubricant temperature were observed when using the different constitutive models. The sensitivity of TEHL simulation results to the choice of constitutive models for lubricants is highlighted by this study, emphasizing the importance of precisely selecting the appropriate models for specific applications.
