为了研究储罐内原油的温度变化规律，采用小波有限元法、传统有限元法和试验相结合的方法进行了数值模拟。首先，在热有限元理论和小波理论的基础上，建立了热小波有限元。建立了计算模型和三种边界条件。采用3种方法计算了3种边界条件下储罐内原油24 h内的温度变化规律，结果表明小波有限元法在储罐内原油温度变化规律的数值分析中具有优势。在此基础上，得到了储罐内原油在不同工况下5 h内的温度分布规律。最后总结了原油温度变化的机理。
In order to study the temperature changing rule of the crude oil in the storage tank, the wavelet finite element method, the traditional finite element method and the test were used to carry out the numerical simulation. Firstly, the thermal wavelet finite element was put forward established based on thermal finite element theory and the wavelet theory. And the computational model and three boundary conditions were established. And then the temperature changing rule of the crude oil in the storage tank in 24 h for three boundary conditions was obtained by using three methods, and the results showed that the wavelet finite element method had advantages in the numerical analysis of the temperature changing rule of the crude oil in the storage. And then the temperature distribution rule of the crude oil in the storage tank under different conditions in 5 h was obtained. And the temperature changing mechanism of the crude oil was summarized finally.
