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.

Key words: Plate-type assembly, Flow distribution, CFD
