Abstract
A convergent-divergent nozzle for supersonic expansion of turbine motive fluid is presented wherein the major part of contouring of the flow paths between adjacent nozzles is in the direction between top and bottom walls between adjacent nozzle side walls, the contouring being accomplished by contoured top and bottom nozzle walls which are asymmetrically contoured in an axial direction to define a symmetric flow path therebetween.
Claims31
A convergent-divergent nozzle including:
- a pair of opposed spaced apart side walls;
- a top wall extending between said side walls;
- and
- a bottom wall spaced from said top wall and extending between said side walls;
- said top and bottom walls and said side walls cooperating to define a flow passageway;
- and
- said top and bottom walls being contoured to cooperate with each other to define at least the throat of the nozzle and a divergent section downstream of the throat, said contouring of said top and bottom walls defining a symmetric flow passage therebetween in the direction of flow downstream of said throat.
An array of convergent-divergent nozzles about an axis for delivery of motive fluid to a turbine, each of said nozzles including:
- a pair of opposed spaced apart side walls;
- a top wall extending between said side walls;
- and
- a bottom wall spaced from said top wall and extending between said side walls;
- said top and bottom walls and said side walls cooperating to define a flow passageway;
- and
- said top and bottom walls being contoured to define at least the throat of the nozzle and the divergent section of the nozzle, said contouring of said top and bottom walls of each nozzle being asymmetric with respect to said axis and defining a symmetric flow passage between said top and bottom walls in the direction of flow downstream of said throat.
An array of convergent-divergent nozzles about an axis of a turbine for passage of motive fluid at supersonic speed, each of said nozzles including:
- a pair of opposed spaced apart side walls;
- a top wall extending between said side walls;
- and
- a bottom wall spaced from said top wall and extending between said side walls;
- said top and bottom walls and said said walls cooperating to define a flow passageway;
- and
- said top and bottom walls being contoured to define at least the throat of the nozzle and the divergent section of the nozzle, said contouring of said top and bottom walls of each nozzle being asymmetric with respect to said axis and defining a symmetric flow passage between said top and bottom walls in the direction of flow downstream of said throat.
An array of convergent-divergent nozzles about an axis of a turbine for passage of motive fluid at supersonic speed, each of said nozzles including:
- a pair of opposed spaced apart side walls;
- a top wall extending between said side walls;
- and
- a bottom wall spaced from said top wall and extending between said side walls;
- said top and bottom walls and said side walls cooperating to define a flow passageway;
- and
- said top and bottom walls being contoured to define at least the throat of the nozzle and the divergent section of the nozzle, said contouring of said top and bottom walls of each nozzle defining a symmetric flow passage between said top and bottom walls in the direction of flow downstream of said throat.
An array of convergent-divergent nozzles about an axis of a turbine for passage of motive fluid at supersonic speed, each of said nozzles including:
- a pair of opposed spaced apart side walls;
- an outer wall extending between said side walls;
- and
- an inner wall spaced from said top wall and extending between said side walls;
- said outer and inner walls and said side walls cooperating to define a flow passageway;
- and
- said outer and inner walls being contoured to define at least the throat of the nozzle and the divergent section of the nozzle, said contouring of said outer and inner walls of each nozzle defining a symmetric flow passage between said top and bottom walls in the direction of flow downstream of said throat.
