The Application of the Method for Variable Cross section Pipes in Controlling the Spin Velocity of a Turbine Alternator

This paper describes the foundational priciple of the application of the variable cross section piping method in controlling the spin velocity of a turbine alternator and gives the mathematic formulas for computing the contraction ratio,divergence ratio,total pressure in partition ,exit velocily, flow and shock wave position of the variable cross section pipe according to the theory on pneumatics,In addition, this paper gives practical computation examples so as to provide systematic references for the techmicians who apply the technololgy.
