The dynamic characteristics of the annular pressure seal employed in pumps have been theoretically deduced with consideration of the effect of elastic deformation due to the high pressure difference. Turbulent flow is assumed in both circumferential and axial directions, 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 previousely published author's results in the stiffness, damping and add mass coefficients.
