摘要: A turbine nozzle includes outer and inner bands integrally joined to a vane having a three-pass serpentine flow circuit between opposite pressure and suction sidewalls. The outer band includes an inlet for channeling cooling air into a first channel of the circuit located behind a leading edge of the vane. A first outlet is disposed in the inner band at the bottom of the first channel where it joins the second channel of the circuit. A second outlet is also disposed in the inner band at the bottom of a third channel of the circuit which is disposed in flow communication with the second channel. The first channel behind the leading edge is smooth except for corresponding rows of first and second turbulators spaced laterally apart. The first turbulators bridge the pressure and suction sidewalls directly behind the leading edge, and the second turbulators are disposed behind the suction sidewall.

A row of venturi slots commences inside the airfoil at the cooling circuit and terminates near the trailing edge. Each of the venturi slots includes an inlet, converging portion, throat, diverging portion, and outlet in serial flow communication from the cooling circuit. The converging portion is comparable in chordal length with the throat.

摘要: A system and method of routing both caller-paid and toll-free telephone calls includes a local exchange network and an interexchange network in communication with a call routing processor. The call routing processor receives status information on at least two call service centers and provides routing instructions to both the interexchange and local exchange networks. The method includes the steps of a call controller in a local exchange network communicating with a call routing processor also in communication with an interexchange network, the call controller identifying calls to call service centers and requesting instructions from the call routing processor.

摘要: A turbine blade with improved tip cooling includes an airfoil having a tip cap and a tip wall extending outwardly from the tip cap. A recessed portion of the tip wall forms a tip shelf. At least one tip shelf hole extends through the tip shelf in flow communication with an internal airfoil cooling circuit. At least one tip wall opening extends through the recessed portion of the tip wall radially outward of the tip shelf in flow communication with the internal cooling circuit. The recessed tip wall portion may be tapered from a wider base to a minimum thickness. In a cooling method, cooling air channeled through the tip wall openings joins and mixes with a stream of hot combustion gases downstream of where cooling air channeled through the tip shelf openings joins and mixes with the stream of hot gasses to enhance convection cooling of the blade tip. A system for cooling a blade includes at least one tip shelf hole and at least one tip wall opening for channeling cooling air from an internal cooling circuit toward a stream of hot combustion gases for improved cooling of at least the blade tip.
