摘要：

A General Design Equation for Confined Impinging Jets (CIJ) is proposed here, giving the prediction of the position of the opposed jets' impingement point. This equation was validated from numerical and experimental results, using fluids with viscosity ratios between 1 and 9 and density ratios between 1 and 10, both values within the industrial range of application of CIJs. The impingement point position is crucial for achieving effective mixing in CIJs, enabling the reactor's design at optimal operational conditions. The general design equation considers the stoichiometry ratio, the fluids' viscosity and density, and the reactors' dimensions. This paper also establishes a methodology for the design of working conditions and the reactor's design for the onset of the chaotic flow regime in CIJs.
