...Bugra H. Ertas; John M. Vance The objective of the following work was to determine frequency-dependent rotordynamic force coefficients for a new annular gas damper seal design. Both rotating and nonrotating experimental tests are presented for inlet pressures at 1000 psig ( 69 bar ) , a frequency...
