Abstract: According to the structural characteristic of the nozzle-loop,a grid calculation model of nozzle-loop was generated by using tetrahedral unstructured grid and thin & thick grid meshing method.And,numerical simulation was performed for the 3-D flow field of nozzle-loop,providing in detail the interior flow characteristic of single nozzle and the outflow flux of nozzle-loop.The results lay a firm basis for further research of nozzle-loop's flux distribution trait.
