In this paper ,CFD analysis is carried out to study the single fuel element and the coolant channel flow field of the Inverted Pressurized Water Reactor (IP‐WR) using commercial CFD code FLUENT ,which analyses and compares the ther‐mal‐hydraulic characteristics of different grid size .The calculation results show that the dimensions of the IPWR fuel cell has greater influence on the temperature and heat transfer characteristics of coolant ,and the study provides preliminary reference and basis for the next design of the IPWR fuel cell ,fuel assembly ,reactor core and the thermal‐hydraulic analysis .
