Nonlinear transient analysis of water lubricated bearing in the turbulent regime
Influence of turbulence on the stability characteristics of a water lubricated journal bearing is analyzed. Locus of the journal centre is plotted using the non - linear transient analysis method for different flow regimes of the bearing subjected to three different types of loading. The bearing groove angles of 18<sup>o</sup> and 36<sup>o</sup> is considered for the analysis. Turbulent coefficients are incorporated in the modified form of Reynolds equation which is solved using the 4th order Runge-Kutta method. The path traversed by journal centre is generated for different loading conditions and the stability of the bearing is examined. For periodic and fluctuating rotating loads, the journal centre traversed shorter path and reached stable position when the flow regime changed from laminar to turbulent.
