The numerical modeling of non-Newtonian lubricant flows in titling pads thrust bearing is developed to predict some interesting factors in industrial view point. It means parameters such as load, friction and power loss whose evaluation contributes strongly to improve the design and performances of the titling pads thrust bearing. The non-Newtonian rheological model chosen is the power law because of its large domain of use. The dynamic field is described through the resolution of the generalized Reynolds equation and the thermal effects, due to the lubricant shearing, is taken into account through a global thermal balance. The discretisation of equations is made by the finite differences scheme.
