As a consequence of heating the slider is deformed and is assumed to take a parabolic <br>shape. Also the asperities expand leading to smaller effective film thickness. Two different types of surface roughness are considered: <br>longitudinal roughness and transverse roughness. Christensen’s stochastic approach is used to derive the Reynolds-type equations. <br>Density and viscosity are considered to be temperature dependent. The modified Reynolds equation, momentum equation, continuity <br>equation and energy equation are decoupled and solved using finite difference method to yield various bearing characteristics. From <br>the numerical simulations it is observed that the performance of the bearing is significantly affected by the thermal deformation of the <br>slider and asperities and even the parallel sliders seem to carry some load. <br> </p>}, number={3}, publisher={Mustafa BAYRAM}
