In this study, the performance of a Tesla valve, integrated into Automatic Recirculation Control (ARC) valves used in industrial applications, is investigated through numerical simulation. The primary objective was to analyze the influence of key geometric parameters of the valve on flow characteristics, including flow rate, pressure drop, and cavitation phenomena. The governing equations were solved using the finite volume method in ANSYS CFX, and the numerical results were validated through comparison with experimental data. The parametric study was conducted in two phases. In the first phase, under a constant pressure drop, the effects of body diameter, stage diameter, stage angle, and the number of stages on flow rate were examined. The results indicated that increasing the diameter and reducing the stage angle can enhance the flow rate by up to 45%, whereas variations in the number of stages had minimal impact on flow rate. In the second phase, the effects of the aforementioned parameters were assessed under varying pressure drops. These results also revealed a direct correlation between pressure drop and flow rate, with trends consistent with the first stage. Furthermore, pressure distribution and cavitation analysis demonstrated that cavitation is inevitable at the valve's downstream section due to a sharp pressure drop. The findings of this study provide valuable insights for the optimal and customized design of Tesla valves in ARC systems,.
