This paper deals with the effect of turbulence on stability characteristics of an externally adjustable fluid film bearing having a design configuration as illustrated by Shenoy and Pai. The time dependent form of Reynolds equation is solved numerically using the finite-difference method. Linearized turbulence model of Ng and Pan is incorporated in the solution scheme. Dynamic coefficients are determined using the method of linearization of bearing reactions. A study with various adjustments predicts that a bearing with negative radial and negative tilt adjustment configuration and operating in turbulent regime results in superior stability as compared to a conventional fluid film bearing.
