Convergent-tapered annular seals analysis for rotodynamic coefficients. Academic Article uri icon


  • A combined analytical and computational method is developed to calculate the pressure field and dynamic coefficients for tapered high pressure annular seals typical of neck ring and interstage seals employed in multistage centrifugal pumps. Numerical results are presented and compared to previous results for straight and tapered seals. (from author's abstract)
