The dynamic characteristics and stability of the annular pressure seal employed in pumps have been theoretically deduced with consideration of the effects of elastic deformation due to the high pressure difference. Turbulent flow is assumed in both circumferential and axial direction, and the deformation of the seal and the shaft is governed by the linear theory of elasticity. The results derived herein considering the elastic deformation are compared with the previously published author’s results [3] in the stiffness, damping, and add mass coefficients.
