shows, the pressure profiles are symmetric with
respect to Y¼0 plane. Also, the asperity pressure profiles have a
peak at each side which is due to local decrease in the film
thickness. Also, for the case of rough surfaces, the asperity
pressure exists at the sides beyond the points where the hydrodynamic
pressure becomes negligible. This is again more visible
for the highest roughness value and affects the total pressure
distribution.
