摘要:
对金属纤维毡多孔介质-钠液的单元和多单元模型在不同热流密度下进行双向热流固耦合模拟,分析其压降和骨架微观变形机制,并进行了多孔介质水力性能测试,验证模型可靠性。结果表明:在层流和湍流时,压降和变形都随流速即所受热流密度的增大而增大。多单元模型骨架的最大变形量比单元模型明显增大。层流时,当入口流速或热流密度随时间线性变化时,其变形量也随之线性变化。
Abstract:
Numerical simulation of single-unit and multi-unit models in porous media(metal felts)-liquid sodium system was investigated by thermal fluid structure coupled method to obtain pressure drop and skeleton deformation of porous media in micro-scale. Hydraulic performance test of porous media provided validation for the reliability of the models. Results showed that pressure drop and deformations in the models were increased with increasing of the velocities of heat fluxes in both laminar and turbulent flows. The maximum deformation of the multi-unit model was much larger than that of the single-unit model. The amount of deformation varied linearly with changing linearly the heat fluxes or input velocities in the laminar flow.
