Singular perturbation problem for the incompressible Reynolds equation
Electronic Journal of Differential Equations, 2006 We study the asymptotic behavior of the solution of a Reynolds equation which describe the behavior of the fluid between two closes surfaces as the distance between the two surfaces locally tends to zero.

Optimization of the Colebrook-White Equation based on experimental data [PDF]
مهندسی مکانیک شریف, 2022 Friction plays an important role in velocity distribution, shear stress, boundary layer, energy loss, and erosion. In the pressure drop, the friction factor has a direct relation with the Reynolds Number in smooth, turbulent, and transitional flows from ...

Effect of hydromagnetic squeeze film between non-porous rough triangular plates [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 The current investigation analyse the impact of hydromagnetic squeeze film between non-porous rough triangular plates. The bearing surface are viewed transversely rough. The Christensen and Tonder model is embraced for transverse roughness.

International Journal of Applied Mechanics and Engineering, 2021 Since the 1960s, all studies have assumed that a film thickness “ h ” provides a unique pressure field “ p ” by resolving the Reynolds equation. However, it is relevant to investigate the film thickness unicity under a given hydrodynamic pressure within ...

Efficient rotordynamic simulations with semi-analytical computation of hydrodynamic forces [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023 A common problem in transient rotordynamic simulations is the numerical effort necessary for the computation of hydrodynamic bearing forces. Due to the nonlinear interaction between the rotordynamic and hydrodynamic systems, an adequate prediction of ...
