EFFECTS OF FLUID INERTIA AND TURBULENCE ON THE FORCE COEFFICIENTS FOR SQUEEZE FILM DAMPERS. Conference Paper uri icon

abstract

  • The effects of fluid inertia and turbulence on the force coefficients of squeeze film dampers are investigated analytically. Both the convective and the temporal terms are included in the analysis of inertia effects. The analysis of turbulence is based on friction coefficients currently found in the literature for Poiseuille flow. The effect of fluid inertia on the magnitude of the radial direct inertia coefficient (i. e. , to produce an apparent 'added mass' at small eccentricity ratios, due to the temporal terms) is found to be completely reversed at large eccentricity ratios. The reversal is due entirely to the inclusion of the convective inertia terms in the analysis.
