| Abstract: | This investigation is concerned with the prediction of the frictional behavior of non-Newtonian fluids in a statically loaded journal bearing. The pressure distribution, friction and bearing load capacity are obtained for various values of the flow behaviour index, n. For the pseudoplastic fluids (n<1) the load carrying capacity and the friction forces are decreased, while shear thickening fluids (n>1) exhibited increases in the friction forces and load. The coefficient of friction was found to decrease as the value of n is increased, provided the dimensionless load exceeded a certain value |
