摘要:	本研究主要分成兩部分，第一部分是乾式貯存系統中密封鋼筒受環向焊接的溫度場及殘餘應力場的參數分析，第二部分是太陽能光電模組的環境風速改變對太陽能板的溫度改變導致光電效率的影響。在乾式貯存密封鋼筒方面，研究重點在於焊接過程中的熱傳導及殘餘應力分佈，透過有限元素法進行數值模擬。分析結果顯示，焊接熱源對鋼筒之溫度場和應力場的影響顯著，不同的焊接參數會導致不同的溫度場，殘餘應力場則因材料已進入塑性變形而變化並不如溫度場一樣顯著。在太陽能板方面，研究探討了不同風速條件下太陽能板的溫度變化，並模擬了水冷系統的應用。結果顯示，風速對太陽能板溫度有明顯影響，水冷系統可以有效降低太陽能板的工作溫度，提高其效率。結合風速與水冷系統的應用，可以進一步提升太陽能板的散熱性能。本研究主要使用有限元素法軟體ABAQUS進行模擬，根據參考文獻提供的模型幾何、材料參數、初始條件和邊界條件，建立數值分析模型，再將模擬結果與文獻中提到的物理場數值分析結果或實驗數據和觀測結果進行比較。 ;This study is divided into two main parts. The first part focuses on the parametric analysis of temperature fields and residual stress fields in the sealed steel cylinders of dry storage systems, specifically in relation to circumferential welding. The second part examines the impact of changes in environmental wind speed on the temperature of solar photovoltaic modules and how this temperature change affects their photovoltaic efficiency. In the aspect of dry storage fuel canister, the focus is on the heat conduction and residual stress distribution during the welding process, utilizing finite element method (FEM) for numerical simulation. The analysis results show that the welding heat source significantly affects the temperature and stress fields of the steel cylinder. Different welding parameters lead to different temperature fields, while the residual stress field varies less significantly due to the material entering plastic deformation. The second part examines the impact of different wind speeds on the temperature and efficiency of solar panels, including a simulation of a water cooling system. The findings indicate that wind speed significantly influences panel temperature, and a water cooling system can effectively reduce the working temperature, thereby improving efficiency. Combining wind speed and water cooling further enhances the heat dissipation performance of solar panels.. ABAQUS software is used for simulation, with models built based on parameters from reference literature. Simulation results are compared with data from the literature to validate the findings.
