Book Description
"The design and the experimental investigation of a 3.75-inch-mean-diameter partial-admission two-stage turbine are presented herein. The investigation was made to determine the effect on two-stage-turbine performance of a change in the axial distance between stages for a turbine with partial admission in the first stage. Accordingly, the turbine was designed with 31.3-percent admission in the first stage, full admission in the second stage, and provision for changing the axial distance between stages. The results of the two-stage investigation are presented for each of the axial distances between stages of 0.25, 0.50, 0.75, 1.00, 1.50, and 2.00 inches. The results of the first-stage investigation are also presented, together with a calculated efficiency for the second stage, at each value of stage spacing as calculated from the two-stage and first-stage results."--Page 1

Book Description
A three-inch mean diameter, two-stage turbine with partial admission in each stage was experimentally investigated over a range of admissions and angular orientations of admission arcs. Three configurations were tested in which first stage admission varied from 37.4 percent (10 of 29 passages open, 5 per side) to 6.9 percent (2 open, 1 per side). Corresponding second stage admissions were 45.2 percent (14 of 31 passages open, 7 per side) and 12.9 percent (4 open, 2 per side). Angular positions of the second state admission arcs with respect to the first stage varied over a range of 70 degrees. Design and off-design efficiency and flow characteristics for the three configurations are presented. The results indicated that peak efficiency and the corresponding isentropic velocity ratio decreased as the arcs of admission were decreased. Both efficiency and flow characteristics were sensitive to the second stage nozzle orientation angles. Turbine performance, Two-stage partial admission turbine, Impulse turbine.
