Influence of transport coefficients’ dependence on temperature for gas flow in microbearing

The paper presents an analytical solution for the non-isothermal compressible gas flow in a slide microbearing with different temperatures of walls. is defined by Navier-Stokes-Fourier system continuum equations and first order boundary conditions. Knudsen number corresponds to slip (Kn ≤ 10 −1 ) Reynolds moderately high, so inertia needs be included. obtained perturbations approximation that relates second one involves second-order effects: rarefaction, inertia, convection, dissipation, rate at which work done compressing element fluid. presented model analyzes influence dependence transport coefficients on temperature. pressure, velocity, temperature approved comparison results other authors. microbearings can often part MEMS, method serve solving similar shear-driven or pressure-driven problems. gives estimation about error values mass load capacity if are neglected.
