中文摘要
本研究首先利用計算流體力學 模擬單相流在收縮-擴張噴嘴內的流動特性, 並比較純水與純蒸汽條件下,不同流量對流體行為的影響。研究的主要目標是探討過冷水通過噴嘴時發生的氣蝕現象,重點關注蒸汽生成效率與噴嘴內的壓力場。結果顯示,進出口壓力差 是影響氣蝕效率的關鍵因素。此外,透過分析不同幾何參數對相變與流體特性的影響,發現出口半徑與喉部面積 分別是影響空蝕效率與質量流率的主要因素。
鑑於機器學習的最新發展,本研究進一步結合數值模擬結果,進行創新性的分析。透過 CFD 模擬不同流量與幾何條件,建立數據庫,並使用人工神經網路(ANN)與支持向量機(SVM) 預測壓力差與其他流體特性。經過準確度評估,結果顯示 ANN 在本研究中表現更為優異,在大多數情況下決定係數(COR2)超過
0.95。
Abstract
In this study, we begin by using Computational Fluid Dynamics (CFD) to simulate the flow characteristics of single-phase flow through a converging-diverging nozzle (CD nozzle). Compare fluid behavior changes with different flow rates in pure water and pure steam conditions. The primary objective of this research is to investigate the cavitation that occurs as subcooled water passes through the nozzle. The focus is on the efficiency of steam generation and the pressure field within the nozzle. It was found that the pressure
difference between the inlet and outlet is a key factor influencing cavitation efficiency. Additionally, through a comprehensive analysis of the effects of various geometric parameters on phase change and other fluid properties, it was found that the outlet radius and throat area are the main factors affecting cavitation efficiency and mass flow rate, respectively.

Given the recent advancements in machine learning, this study integrates numerical simulation results to conduct an innovative investigation. Different flow rates and geometries were simulated using CFD to establish a database, and ANN and SVM were employed to predict pressure differences and other fluid properties. After evaluating their accuracy, it was found that ANN was significantly more suitable for this study, achieving determination coefficients exceeding 95% in most cases.
