7 where k is the adiabatic exponent, and where P1 and p1 are the gas pressure and density ahead of the nozzle at the same radius r. Now thatwe know theabsolutevelocityatthechosen radius r, the static temperature T at that radius can be calculated, since the total temperature or stagnation tem perature T, ahead of the nozzle is known from the temperature pro?le of FIG. 2. The static temperature T at the nozzle outlet at the chosen radius 1'may be cal culatedbytheexpression T=T,—- (11) whereJistheheatenergy-mechanicalenergyequivalency factor, and 0D is the constant pressure speci?c heat. Bytheinitial?xingoftangentialMachnumberin versely proportional to radius, we recall from Equation 2 that 8 the spacing between adjacent buckets, or pitch, is pro portional to the radius and hence is greatest at the tip. Hence the “solidity,” which is the ratio of chord to pitch and which is used in the art as an aerodynamic de~ sign parameter related to the bucket entrance and exit angles, is considerably smaller at the tip than at the rootinpriorartdesign. In contrast, in the present invention the bucket angles de?ned by the aforementioned method of velocity dia 10 gram calculation are such as to require greater turning of the ?uid at the tip than at the root, mainly as a con sequence of the reversed entrance angle warp, as illus tratedinFIG.8. Inthiscase,theaerodynamicrequire ments for minimum bucket losses are better suited by Now since <2) (5) 25 Equation 2 may be expressed as _ Vs Tn VH4“ 73X?) And since Equation 12 may be further expressed as It is found that causing the gross area to vary in this manner results in a bucket surface having radial elements whichsubstantiallyconvergeattherotoraxis. Forexam ple, if the bucket cross-section were a circle, the bucket MU=MUR(%) 15 constant “solidity” from root to tip, and hence a chord proportionaltoradius. Inaddition,thebucketmaximum thickness is most suitably made to increase proportional to the chord and hence the radius. This causes the gross cross—sectional area of the bucket to be approximately proportional to the radius squared. The gross area A ispreferablycausedtovarybythepreviouslystated formula where T and TR are the static temperatures of the gas at the nozzle exit at any radius r, and at the root radius rR respectively. 3,135,496 T2 A=ARPDF Image | FLOW TURBINE WITH RADIAL TEMPERATURE GRADIENT
