Abstract

OSCILADOR FLUìDICO DE DESEMPENHO A FRIO APERFEIçOADO. A presente invenção refere-se a um oscilador fluídico (2) adequado para o uso a temperaturas mais frias para gerar um fluxo de exaustão na forma de uma pulverização oscilante de gotas de fluido tem uma entrada (12) para fluido pressurizado, um par de bocais de força (14) configurados para acelerar o movimento do fluido pressurizado, uma trajetória (10) que permite o fluxo do dito fluido pressurizado entre sua entrada (12) aos bocais de força (14), uma câmara de interação (18) que é fixada nos bocais (14) e recebe o fluxo dos bocais, uma saída de fluido (20) a partir da qual a dita pulverização escapa da câmara de interação (18), e um meio para aumentar a instabilidade do fluxo a partir dos bocais de força (14). Em uma primeira modalidade preferida, o dito meio compreende uma protuberância (4) que se estende para dentro a partir de cada lado da trajetória de fluido (10). Em uma segunda modalidade preferida, o dito meio compreende um degrau (24) na elevação de altura do piso dos bocais de força (14) com respeito àquela da câmara de interação (18).
