TITLE: An Experimental Investigation of the Flow through an Axial-Flow Pump AUTHORS: Zierke, Straka, and Taylor JOURNAL PAPER FIGURE(S): 9 PSU/ARL TR 93-12 FIGURE(S): 64 ***************************************************************************** DATA TITLE: Spanwise variation of total-pressure coefficient 32.2% chord axially downstream of the rotor tip trailing edge with IGV index location of 22.0 degrees MEASUREMENT TYPE: Kiel total-pressure probe and wall static-pressure tap MEASUREMENT LOCATION: Total pressure variation measured at 32.2% tip chord axially downstream of rotor tip trailing edge. Static pressure measured on outer casing wall at 32.2% chord axially downstream of rotor tip trailing edge. Inlet guide vanes oriented with a 22 deg. index location. NOMINAL CONDITIONS: vref = 35.0 ft/sec pref = 43.2 psia rho = 1.932 slugs/ft^3 rotor rpm = 260 rpm volumetric flow coefficient = 1.36 rotor tip speed = 47.6 ft/sec rotor balde tip diameter = 1.75 ft rotor blade span = 10.50 inches rotor tip chord = 10.49 inches DATA COLUMNS: 1 -- Location of total pressure measurement in % span (where 0.0 is at hub surface and 100.0 is on outer casing liner) 2 -- Total pressure coefficient = (Ptot - pref) / (0.5 * rho * vref^2) [uncertainty of Cp: 0.005] 3 -- Outer casing static pressure coefficient = (Pstatic - pref) / (0.5 * rho * vref^2) ***************************************************************************** 98.0952 0.9783 0.4815 98.0952 0.9723 0.4802 98.0952 0.9727 0.4810 97.1429 0.9919 0.4784 97.1429 0.9955 0.4798 97.1429 0.9937 0.4814 96.1905 1.0697 0.4815 96.1905 1.0772 0.4805 96.1905 1.0692 0.4795 95.2381 1.1429 0.4795 95.2381 1.1585 0.4827 95.2381 1.1514 0.4805 94.2857 1.1897 0.4814 94.2857 1.1956 0.4810 94.2857 1.2032 0.4803 92.3810 1.3166 0.4812 92.3810 1.3174 0.4803 92.3810 1.3109 0.4787 91.4286 1.3473 0.4788 91.4286 1.3475 0.4807 91.4286 1.3484 0.4809 90.4762 1.3705 0.4802 90.4762 1.3747 0.4811 90.4762 1.3737 0.4800 89.5238 1.3939 0.4801 89.5238 1.3948 0.4803 89.5238 1.3966 0.4812 88.0952 1.4074 0.4805 88.0952 1.4068 0.4823 88.0952 1.4063 0.4810 85.7143 1.4146 0.4798 85.7143 1.4163 0.4818 85.7143 1.4142 0.4824 83.3333 1.4225 0.4803 83.3333 1.4226 0.4810 83.3333 1.4244 0.4817 80.9524 1.4304 0.4814 80.9524 1.4287 0.4818 80.9524 1.4283 0.4809 78.5714 1.4281 0.4809 78.5714 1.4297 0.4808 78.5714 1.4297 0.4802 76.1905 1.4278 0.4799 76.1905 1.4260 0.4798 76.1905 1.4289 0.4814 73.8095 1.4316 0.4825 73.8095 1.4332 0.4816 73.8095 1.4311 0.4812 71.4286 1.4412 0.4812 71.4286 1.4424 0.4820 71.4286 1.4402 0.4808 66.6667 1.4580 0.4808 66.6667 1.4591 0.4809 66.6667 1.4586 0.4826 61.9048 1.4565 0.4826 61.9048 1.4613 0.4818 61.9048 1.4615 0.4819 57.1429 1.4323 0.4811 57.1429 1.4346 0.4819 57.1429 1.4330 0.4804 52.3809 1.4562 0.4816 52.3809 1.4554 0.4821 52.3809 1.4564 0.4807 47.6190 1.4669 0.4807 47.6190 1.4685 0.4819 47.6190 1.4693 0.4833 42.8571 1.4656 0.4807 42.8571 1.4654 0.4819 42.8571 1.4677 0.4804 38.0952 1.4907 0.4817 38.0952 1.4924 0.4829 38.0952 1.4921 0.4818 33.3333 1.4859 0.4844 33.3333 1.4836 0.4816 33.3333 1.4864 0.4822 28.5714 1.4849 0.4832 28.5714 1.4818 0.4830 28.5714 1.4843 0.4810 26.1905 1.4800 0.4804 26.1905 1.4764 0.4817 26.1905 1.4775 0.4811 23.8095 1.4692 0.4826 23.8095 1.4701 0.4837 23.8095 1.4687 0.4839 21.4286 1.4632 0.4829 21.4286 1.4624 0.4821 21.4286 1.4613 0.4826 19.0476 1.4281 0.4843 19.0476 1.4284 0.4804 19.0476 1.4242 0.4832 16.6667 1.3542 0.4845 16.6667 1.3491 0.4825 16.6667 1.3521 0.4826 14.2857 1.3091 0.4834 14.2857 1.3081 0.4832 14.2857 1.3099 0.4829 11.9048 1.3148 0.4825 11.9048 1.3138 0.4838 11.9048 1.3087 0.4839 10.4762 1.3282 0.4842 10.4762 1.3303 0.4837 10.4762 1.3299 0.4829 9.5238 1.3466 0.4814 9.5238 1.3497 0.4845 9.5238 1.3475 0.4839 8.5714 1.3570 0.4832 8.5714 1.3606 0.4852 8.5714 1.3547 0.4832 7.6191 1.3603 0.4838 7.6191 1.3616 0.4835 7.6191 1.3660 0.4833 5.7143 1.3721 0.4836 5.7143 1.3760 0.4832 5.7143 1.3737 0.4827 4.7619 1.3744 0.4855 4.7619 1.3759 0.4831 4.7619 1.3748 0.4836 3.8095 1.3543 0.4826 3.8095 1.3543 0.4832 3.8095 1.3541 0.4844 2.8572 1.2738 0.4819 2.8572 1.2718 0.4826 2.8572 1.2686 0.4831
