| Abstract: | Certain cases of nonsteady motion of a dropping compressible liquid with different laws of friction in conduits (in particular, in main oil pipelines) are considered. Results are presented of a solution of a number of problems of unsteady motion of a dropping liquid in pipes with a square law of resistance and for regimes characteristic of hydraulically smooth pipes, obtained numerically by the method of finite differences (method of nets). A comparison is made to results obtained by linearizing the term containing the square-law friction according to a previous 1] technique. Deviations of the parameters of nonsteady flows for given laws of resistance are studied.Translated from Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 1, pp. 87–94, January–February, 1976. |
