Abstract:Aim.The introduction of the full paper reviews some papers in the open literature,points out what we
believe to be their shortcoming and then proposes our exploration,which is explained in sections 1 and 2.Section
1 briefs the structure of an aeroengine bearing chamber and its parameters.Subsection 2.1 explores mathematically
the oil film/air(containing droplets)two-phase flow inside all aeroengine bearing chamber;subsection 2.2 devel-
ops a numerical model for predicting the lubricant flow inside an aeroengine bearing chamber,with film/droplet/air
interactions taken into consideration.Section 3 uses the CFX commercial software to simulate the pressure and ve—
locity distributions of lubricant flows under certain operation conditions;the simulation results,given in Figs.2
through 7,and their analysis show preliminarily that:(1)there is a wider pressure distribution of the lubricant flow
along the circumference of the bearing chamber than along its axial direction;the velocity distribution is just the op—
posite of the pressure distribution;(2)the pressure of oil film increases with increasing rotational speed;・the pres—
sure inside the bearing chamber increases with increasing oil mass flow rate and sealing air.
Key words:aircraft engines,pressure distribution,flows,bearing chamber,oil/air two—phase flow
