This paper deals with the study of the effect of
axial grooves on thermal behavior and pressure
distribution in a hydrodynamic bearing under the
influence of thermal elastic deformation. The twodimensional Reynolds equation has been numerically
solved using a computer program (Matlab) to find the
values of pressure on the bearing and calculate the net
force, taking into account the effect of both thermal and
elastic deformation on the values of permittivity
(clearance) and then pressure, and their effect on the
Thermal behavior and pressure curve. The results
showed that the axial grooves in the hydrodynamic
bearing contribute to a decrease in the maximum values
of pressure and temperature rates of the bearing and a
decrease in the values of the absorbed power.
