Title of the articleDependencies for calculating the air-jet screen over an industrial bath
Abstract.Problem statement. The purpose of the study is to identify and present, in an accessible form for practical applications, the basic dependencies for the calculation of air screens over industrial baths obtained by the CFD method. The parameters of the interaction of a flat jet flow and a localizing slot outlet in air screens depend mainly on the geometric conditions: the distance between the supply and discharge device l, the distance from the axis of the air screen to the liquid mirror h, width of the slot outlet B. Results. The main results of the research consist in the dependences presented in the dimensionless form, which are required for the calculation of air screens over industrial baths. Such dependencies are given in the form of analytical formulas and in the form of graphs. Because of the complexity of the calculated flows, the analytical description is rather cumbersome and more suitable for a computer calculation program. Graphic materials are available for manual calculations. Conclusions. The significance of the results obtained for the ventilation of industrial buildings is to more fully and correctly take into account the geometric factors in the calculation of air screens over industrial baths. The examples illustrate how to apply the obtained dependencies.
Keywords.air-jet screen, flat jet flow, outlet, air flow, calculation.
