Abstract
In this chapter, the combined impact of viscosity variation, non-Newtonian fluid, and Slip velocity on the squeeze-film attributes of a cylinder and plane plate is analyzed. Using the Barus formula for viscosity and Stoke’s model for non-Newtonian fluid, the modified Reynold’s equation is developed, and later, by considering the variation of viscosity as a function of pressure, the expression for film pressure is determined using the perturbation technique. Also, in the film area with integrating pressure, load-carrying capacity and Squeeze film time are found. According to the findings, using a non-Newtonian fluid as a lubricant and viscosity variation results in an increase in squeeze-film attributes such as pressure, load-carrying capacity, and Squeeze film time, but the effect of slip parameter must be kept at a minimum to improve bearing system performance.
