| Abstract: | The quest for optimal noise‐reduction orifice plates in natural gas pressure regulating valves is often constrained by a fundamental dilemma: high‐fidelity fluid‐acoustic simulations, although accurate, impose prohibitive computational costs that render conventional optimization approaches impractical. To break this stalemate, this paper introduces a novel surrogate‐assisted framework featuring a Query‐by‐Committee (QBC) mechanism that enhances the adaptive capabilities of kriging modeling. Unlike traditional single‐criterion infill strategies, our framework constructs a diverse committee of kriging models using multiple kernel functions. By quantifying the level of "disagreement" among committee members regarding unobserved points, the algorithm intelligently selects the most informative samples, thereby maximizing global prediction accuracy while minimizing simulation calls. Extensive benchmarking against standard test functions demonstrates that the proposed QBC‐kriging achieves a 6.13% higher comprehensive prediction accuracy and an 18.72% lower computational expenditure compared with the classical expected improvement (EI) strategy. In a multiobjective engineering case study focusing on a gas regulator′s orifice plate, the new framework yields a 1.2% enhancement in optimization precision and a 39.6% boost in efficiency. Furthermore, a robustness analysis under varying inlet pressures reveals that the QBC‐derived design maintains stable acoustic performance (4.8%–5.3% reduction, SD = 0.21 dB), whereas the previously optimized design exhibits significantly wider fluctuations (4.1%–8.68%, SD = 1.42 dB). This work offers a practical and scalable optimization pathway for complex fluid‐acoustic systems burdened by high computational expenses. [ABSTRACT FROM AUTHOR] |
