Dynamic Simulation of Closed Cycle Power System for UUV
摘要
Abstract
The closed cycle power system based on Li/SF6 heat pipe reactor is investigated for the purpose of designing high energy density power system of unmanned underwater vehicle(UUV). The moving boundary models of an evapo-rator and a condenser are established based on mass conservation and energy conservation equations with dividing their heat exchangers into different areas. The steady state model of a turbine and the dynamic model of a liquid trap are es-tablished. And the dynamic model of the whole system is built. With step change of the inlet water flow rate of the evaporator, the dynamic characteristics of the key components of the system are obtained by simulation. The results show that with the increase in the inlet water flow rate, the pressure in the tube rises up, the temperature at evaporator outlet decreases, the turbine power output gets higher, and the phase zone lengths of the evaporator and condenser change. When the flow rate decreases, the above behaviors change on the contrary. These models may be applicable to design of UUV power system and its control strategy.关键词
