Abstract

BOMBA DE JATO A presente invenção refere-se a um movimentador de fluido (1) inclui um corpo oco (2) dotado de uma passagem vazada direta (3) de seção tranversal substancialmente constante com uma extremidade de entrada (4) e uma extremidade de saída (5) para a entrada e descarga, respectivamente, de um fluido de trabalho. Um bocal (16) substancialmente circunscreve e abre para o interior da passagem (3) intermediária às extremidades de entrada (4) e saída (5). Uma entrada (10) se comunica com o bocal (16) para introdução de um fluido de transporte e uma câmara de mistura (3A) é formada dentro da passagem (3) a jusante do bocal (16). A geometria interna do bocal e o perfil do furo imediatamente a montante da saída do bocal são colocadas e configuradas para otimizar a transferência de energia entre o fluido de transporte e o fluido de trabalho. Em utilização, através da introdução de fluido de transporte, o fluido ou fluidos de trabalho são atomizados para formar um regime de escoamento disperso de vapor-gotículas com condições de escoamento localmente supersónicas dentro de uma pseudo-veia contraída, que resulta na criação de uma onda de choque de condensação supersónica (17) dentro da câmara de mistura de jusante (3A) por meio da condensação do fluido de transporte. Métodos de movimentar e processar fluidos utilizando o movimentador de fluido também são descritos.JET PUMP The present invention relates to a fluid mover (1) includes a hollow body (2) provided with a substantially constant cross-section straight through passage (3) with an inlet end (4) and a outlet (5) for inlet and outlet respectively of a working fluid. A nozzle (16) substantially circumscribes and opens into the passageway (3) intermediate the inlet (4) and outlet (5) ends. An inlet (10) communicates with the nozzle (16) for introducing a transport fluid and a mixing chamber (3A) is formed within the passage (3) downstream of the nozzle (16). The internal nozzle geometry and hole profile immediately upstream of the nozzle outlet are placed and configured to optimize energy transfer between the carrier fluid and the working fluid. In use, by introducing carrier fluid, the working fluid or fluids are atomized to form a dispersed vapor-droplet flow regime with locally supersonic flow conditions within a contracted pseudo-vein, which results in the creation of a supersonic condensation shockwave (17) within the downstream mixing chamber (3A) by condensation of the carrier fluid. Methods of moving and processing fluids using the fluid mover are also described.
