We consider steady, laminar, compressible lubrication flows in a high-speed two-dimensional journal bearing governed by the appropriate Reynolds equation. The thermodynamic states correspond to pressurized gases and are in the single-phase regime. Si

The aerodynamics effects caused by high-speed trains entering a tunnel may induce many serious engineering problems such as the passenger discomfort, noise surrounding the tunnel entrance/exit and possible damage to the train body and tunnel

We examine the high-speed flow of pressurized gases between non-concentric cylinders where the inner cylinder rotates at constant speed while the outer cylinder is stationary. The flow is taken to be steady, two-dimensional, compressible, laminar, si

We present approximate solutions to the compressible Reynolds equation and the corresponding temperature equation which are valid for large speed numbers in the dense and supercritical gas regime. The flows are taken to be two-dimensional, steady, co

In this study, a compressible thermohydrodynamic (THD) model was developed to examine the flow dynamics of a journal bearing lubricated with supercritical carbon dioxide (sCO2). This model employed a general form of the Reynolds equation governing co

Adaptive lubricants involve binary mixture of synthetic oil and dissolved carbon dioxide (CO2). Unlike conventional lubricant oils, the lubricant viscosity not only varies with the temperature within the bearing, but also can be directly adjusted thr

This study developed a novel two-way dynamic coupled numerical model to simulate moving solids in free surface flows. The fluid flows and hydrodynamic pressures are simulated by a Large Eddy Simulation model, and the free surface is tracked by the Vo

This study uses a three-dimensional, compressible, turbulence model to investigate the pressure waves generated by two trains passing each other in a tunnel. The turbulent flow around the train bodies is computed by the RNG k–ɛ turbulence model; a

We derive the Reynolds equation corresponding to steady, laminar, two-dimensional, compressible flows of single-phase Navier-Stokes fluids in a thin gap between a stationary surface and one translating with constant speed. The thermodynamic state of
