| Abstract: |
| A multi-slit tapered stock distributor was introduced， and the numerical simulation and analysis of the distributor were carried out by using the computational fluid dynamics method， and its structure was optimized. The preliminary study found that, the distribution of the stock of multi-slit distributor was better than the Branch pipe distributor， the maximum error was reduced by 0.9%. After optimization， when the slit length was 185 mm， the radius of multi-slit entrance was 7.5 mm， the radius of exit arc was 265 mm， and the length of diffuser was 90 mm， the maximum error of the distribution of each slit was 1.43%. Futhermore， based on the structure principle， the slit width could be achieved on-line adjustment， in order to further reduce the flow distribution error， and reduce or eliminate the circulation reflux． |
