Abstract:

本文研究了磁流体动力学效应对聚变堆液态包层中液态金属流动和传热的影响，开发了MHD流动与传热分布数值模拟程序，采用数值方法对聚变堆液态包层中的流动传热现象进行了模拟。该数值模拟程序基于4步投影法计算强磁场下包层中的流场分布，利用有限体积法得到了流道中的温度分布，并通过标准算例和能量守恒的方法对数值模拟的结果进行验证，为开展聚变堆包层中液态金属的流动与传热特性的研究提供了参考。
The effect of magnetohydrodynamic effect on the flow and heat transfer of liquid metal in liquid blanket of fusion reactor is studied. A numerical simulation program of MHD flow and heat transfer distribution is developed. The flow and heat transfer phenomena in liquid blanket of fusion reactor are simulated by numerical method. The numerical simulation program is based on the four-step projection method to calculate the flow field distribution in the blanket under strong magnetic field. The temperature distribution is obtained by using the finite volume method. The results of numerical simulation are verified by standard examples and energy conservation methods. It provides a reference for the study of the flow and heat transfer characteristics of liquid metals in the blanket of fusion reactor.
