Transition Duct Geometry Polynomial Coefficients The superellipse of the transition duct boundary is given by (y/a)**(eta) + (z/b)**(eta) = 1 where a,b and eta are functions of streamwise position x. The quantities (a/R), (b/R) and eta are given by polynomials of the form c0 + c1*(x/R) + c2*(x/R)**2 + .. + c5*(x/R)**5 The tables below give the coefficients c0..c5 for a,b and eta at the various x intervals. The radius R of the inlet circular duct is 102.15 mm. a/R b/R eta x/R .le. 1.0 c0 1.000000000 1.000000000 2.000000000 c1 0.000000000 0.000000000 0.000000000 c2 0.000000000 0.000000000 0.000000000 c3 0.000000000 0.000000000 0.000000000 c4 0.000000000 0.000000000 0.000000000 c5 0.000000000 0.000000000 0.000000000 1.0 .le. x/R .le. 1.96 c0 0.875682170 1.110219900 8.483346500 c1 0.386998680 -0.343102010 -21.329880000 c2 -0.387831440 0.343807210 26.148548000 c3 0.096543991 -0.085532496 -15.173079000 c4 0.041969148 -0.037245857 4.361414300 c5 -0.013362557 0.011853259 -0.490349400 1.96 .le. x/R .le. 2.92 c0 -0.373365600 2.216277900 1.097110900 c1 3.351019300 -2.968311200 2.362357900 c2 -3.279659000 2.905634800 -2.878524200 c3 1.552321700 -1.375475300 2.062091200 c4 -0.336649300 0.298313020 -0.641363010 c5 0.027262234 -0.024157751 0.080685615 2.92 .le. x/R .le. 4.125 c0 14.292266000 -10.787227000 -1858.441200000 c1 -19.643522000 17.419488000 2828.735300000 c2 11.204615000 -9.936079200 -1704.806300000 c3 -3.038098800 2.694140300 508.598460000 c4 0.396892830 -0.351957700 -74.960370000 c5 -0.020128978 0.017849940 4.365165200 x/R .ge. 4.125 c0 1.546359100 0.515449880 10.000000000 c1 0.000000000 0.000000000 0.000000000 c2 0.000000000 0.000000000 0.000000000 c3 0.000000000 0.000000000 0.000000000 c4 0.000000000 0.000000000 0.000000000 c5 0.000000000 0.000000000 0.000000000
