LIQUID-GAS JET APPARATUS AND VARIANTS

摘要

The present invention pertains to the field of jet-generation techniques and essentially relates to a liquid-gas jet apparatus. In this apparatus, the ratio between the surface area at the smallest cross section of the mixing chamber and the surface area at inlet cross section of said chamber varies between 0.005 and 0.392. The straight line defining the conical surface of the tapering section of the mixing chamber or the tangent line for every point in the curved generatrix of the surface of the tapering section in the mixing chamber are inclined at an angle of between 30' and 10~ relative to the axis of said mixing chamber. In another embodiment, the ratio between the surface area at the smallest cross section of the mixing chamber and the surface area at inlet cross section of said chamber varies between 0.005 and 0.392. The straight line defining the mixing-chamber conical surface that tapers in the flow direction or the tangent line for every point in the curved generatrix of the surface of the mixing chamber that tapers in the flow direction are inclined at an angle of between 30' and 10~ relative to the axis of said mixing chamber. A liquid-gas jet apparatus realised according to the abovementioned parameters has an improved performance index.
