Pagination or Media Count:
The two-phase thrust bearing is analyzed near the axis of rotation where the radial pressure gradient is non zero and the viscosity is negligible for the gaseous phase. The analysis agrees with the previous work by Sparrow and Gregg Trans of ASME, Series E, 81113-120, 1959 for condensate thickness for the limiting case of zero pressure gradient. With radial pressure gradients, the condensate thickness is seen to have the chance of re-evaporation due to the change of vapor temperature in the radial direction. The sensitivity of the condensate thickness to temperature difference is noted.
