基于一维分布参数法的螺旋管蒸发器动态建模
Dynamic Modeling of Spiral Tube Evaporator Based on One-Dimensional Distributed Parameter Method
摘要
Abstract
The metal fuel with higher energy density has become an important role in development of underwater ther-mal power systems. In this paper, the one-dimensional distributed parameter method is employed to establish a dynamic model of the spiral tube evaporator in a Li/SF6 heat pipe reactor. Simulations are performed by changing different input parameters, and the results are compared with that of the moving boundary method. It is indicated that the one-dimen- sional distributed parameter model can better represent the real system, and is able to reflect the dynamic response of the system more accurately. The computational efficiency approaches that of the moving boundary model if suitable formula derivation and proper algorithm are adopted. This model is robust with respect to sudden change of the input load. This research may provide the basis for design, control and real-time simulation of underwater thermal power systems.关键词
