Title (EN) LIQUID-GAS JET APPARATUS
(FR) APPAREIL A JETS DE GAZ ET DE LIQUIDES
Abstract:
(EN) The present invention relates to jet apparatus techniques and is characterised in that the surface area of the minimal cross section of the mixing chamber represents from 0.1 to 7.98 times that of the minimal cross section of the active fluid nozzle. An apparatus having the dimensions defined by the above-mentioned relation exhibits an increased performance index due to the cut in energy losses.
(FR) Cette invention se rapporte aux techniques des appareils à jets et se caractérise essentiellement en ce que la surface de la section minimale de la chambre de mélange représente de 0,1 à 7,98 fois celle de la section minimale de la buse active pour le liquide. Cette invention permet d'obtenir un appareil à jets qui, lorsqu'il possède les dimensions définies par la relation susmentionnée, offre un meilleur indice de rendement grâce à la réduction des pertes d'énergie.
