The compressible elastohydrodynamic (EHD) lubrication of two surfaces under line contact has been investigated in steady state operating conditions. The modified Reynolds equation with non-Newtonian fluids has been formulated using Carreau viscosity model. The simultaneous systems of modified Reynolds and elasticity equations with boundary conditions were solved numerically using Newton Raphson technique. The performance characteristics of the elastohydrodynamic lubrication under two surfaces in line contact were calculated and presented for varying the non-Newtonian Carreau viscosity model parameters. The pressure profile, film thickness profile, load capacity were investigated in both static and dynamic conditions. This simulation showed the significant effect of model parameters on elastohydrodynamic lubrication under heavy load conditions.
