Tilting tile journal bearings are widely used in rotary condensers. The oil film flow in them gradually gets rid of laminar flow and develops into turbulent flow. To accurately analyze this kind of superlaminar flow flow process, it is necessary to correctly describe and simulate the superlaminar flow flow process. In this paper, direct numerical simulation is used to study the superlaminar flow and find that the superlaminar flow is near-wall turbulence. Aiming at the near-wall turbulence with a low Reynolds number, the SST model modified by a low Reynolds number is used for simulation. The simulation results are compared with the experimental and direct numerical simulation results. The results show that: The SST model modified by low Reynolds number can accurately predict the transition from laminar flow to turbulent flow, and verifies that the phenomenon of superlaminar flow in tilting journal bearing is Taylor-Couette near-wall turbulence.
