A Multicoefficient Slip-Corrected Reynolds Equation for Micro-Thin Film Gas Lubrication

[摘要] This work investigates and analyzes the performance ofconventional slip models among various regimes of Knudsen numberand developes a new multicoefficient slip-velocity model, by usingTaguchi quality control techniques and numerical analysis. Amodified Reynolds equation is also derived based on the newslip-flow model. The multicoefficient slip model and itsslip-corrected Reynolds equation are suitable to a wide Knudsenrange from slip to transition regime. In comparison with otherconventional slip models, it is found that the current resultshave a better agreement with the solution obtained from thelinearized Boltzmann equation and direct simulation of Monte Carlomethod (DSMC).
