高功率脉冲加热条件下燃料模块流动传热特性研究
Study on Flow and Heat Transfer Characteristics of Fuel Module under High Power Pulse Heating
摘要
Abstract
In the Z-Pinch fusion-fission hybrid reactor , the fusion neutron source is released in the form of pulse ,and the intense pulse characteristic would exist in the energy-releasing process of the fission fuel .On the basis of extracting the fuel module from the water cooling blanket ,the flow and heat transfer characteristics were simulated and analyzed using Fluent program and lumped parameter method ,respectively .The practicability of lumped parameter method in simulating pulse heating was demonstrated by Fluent program ,and the effects of material thermophysical property on flow and heat transfer characteristics were analyzed .The calculation results show that lumped param-eter method can be used in simulating the flow and heat transfer under pulse heating . The outlet temperature and flow rate would oscillate under pulse heating ,and the oscil-lation could be weakened by increasing the heat capacity of fuel and decreasing the thermal conductivity of tube .关键词
