| 用并行算法求解了圆柱通道内的不可压层流流动。采用有重叠的条形区域分裂法对计算域进行分区，分别求解动量方程和压力校正方程，对压力校正方程采用块修正法来加速线代数方程的收敛速度。计算结果表明有较好的并行加速比和并行效率。 |

| Abstract: |
| uthors use the parellel calculation method to solve the incompressible viscous laminar flow in cylindrical passage. The idea is that the all calculated area is divided into sub-ranges by the strip range split method with overlaping, and the momentum and pressure correction equations are distributedly parallelly solved in every sub-range respectively; For the pressure correction equation, the block correction method is used to quicken the convergent speed of linear algebraic equatins.The calculation aims at probing the road using parallel calculation method to calculate complex flow field. In order to popularize, the calculation is carried out on IBM-386 micro-computer outfitting TRANSPUTER boards. In the condition of the calculated example the area is divided into 4 sub-ranges, the parallel quickened ratio is 2. 82, and the parallel efficiency is 70. 5%. The practical calculated example states that the paralleled calculation method possesses a good prospect. |
