The results of using the CONV-3D code to model incompressible fluid flows in round tubes in laminar, transient, and turbulent regimes are presented. The results of modeling with different Reynolds numbers are compared with the Poiseuille parabola and the Blasius formula. It is shown that the code satisfactorily models the flow of an incompressible fluid in laminar, transient, and turbulent regimes and can be used to analyze such flows in different applications.

使用 Conv-3d 代码在层流、瞬态和湍流状态下对圆管中不可压缩流体流动进行建模

介绍了使用 CONV-3D 代码模拟层流、瞬态和湍流状态下圆管中不可压缩流体流动的结果。将不同雷诺数建模的结果与泊肃叶抛物线和布拉修斯公式进行比较。结果表明，该代码令人满意地模拟了层流、瞬态和湍流状态下不可压缩流体的流动，并可用于分析不同应用中的此类流动。
