| 摘 要： | Numerical method of flow field of laser servo-controlled strand window bomb was studied and discussed. Stream function and vorticity method of axisymmetric, steady, incompressible flow field was also studied and discussed. Axisymmetric finite difference stream function-vorticity equations on interior points and the points near oblique boundary were derived. Boundary conditions were given and initial interative field was offered before calculation. Cross-bidirectional scanning method was used for increasing parameter transmission rate and relaxation method which could increase convergent stability was applied. At last, the flow field of laser servo-controlled strand window bomb was shown, including motion patterns and vorticity flow scatter diagrams. The solutions were in concordance to the solutions by Mills et al. and the theories by Pan and Acrivos.
