摘要

板状燃料组件被广泛应用于研究堆中，组件内的流量分配是设计时需要考虑的一项重要内容。计算流体动力学（Computational Fluid Dynamic

CFD）方法是研究流量分配的重要手段，但有限的计算资源限制了其在板状燃料组件流量分配研究中的推广。针对板状燃料组件冷却剂流道狭长、封闭的特点，提出了部分建模迭代求解的计算方式，将无流量分配组件与有流量分配组件两种工况下各流道流量的计算值与直接完整建模的结果进行了对比，最大误差分别为0.56%与0.81%。鉴于前者对计算资源的需求远小于后者，部分建模迭代求解可以作为板状燃料组件流量分配CFD研究的合理可信的优化方案。

Abstract

Background:

Plate-type assembly is widely used in research reactors. Flow distribution inside the assembly is a key factor in design process. Computational fluid dynamics (CFD) method is an important way for flow distribution calculations. However

huge requirements on computing resources limit the application scope of CFD method.

Purpose:

The aim is to invest the CFD method in the flow distribution with smaller requirements on computing resources.

Methods:

New developed CFD method by partial modeling and iterating is used.

Results:

Using the traditional CFD and newly developed method

flow distribution calculations are done toward plate-type assembly with and without the flow distributor

and the maximum differences are 0.81% and 0.56%

respectively.

Conclusion:

The partial modeling and iterating method could optimize CFD simulations on flow distribution of plate-type assembly accurately

economically and quickly.
