A-1-1 Thermo-molecular Gas-film Lubrication(t-MGL) Analysis of Pressure Produced by Boundary Temperature(Static characteristics for arbitrary l-dim temperature distributions)

Abstract

This paper analyzes the static lubrication characteristics of a slider over a running boundary wall with arbitrary local temperature distributions using the thermo-molecular gas-film lubrication(t-MGL) equation.We obtain two approximate solutions:(i) the linearized solution when the temperature deviation is small(τ_w≪1)and arbitrarily distributed(Superposition method),and(ii) the solution when the bearing number is very large(Λ→∞).We numerically calculated the static lubrication characteristics and verified the validity of the superposition method and the solution for Λ→∞.We also calculated the flying characteristics for various temperature distributions produced by laser heating.
