【摘要】 本文讨论了血液在大血管中的非定常振荡流动问题,导出了一组血液流动的速度分布、压力分布公式。分析表明,本文公式既适用于入口区域的流动,也适用于远离入口区域的流动;既可描述定常流动,也可描述非定常的振荡流动。数值算例还表明,本文结果不但和已有的理论结果相一致,而且较之简单,并和实验结果相当吻合。更多还原

【Abstract】 In this paper the problem on the blood flow in a largevascular tube under unsteady oscillatory condition is discussed anda set of formulas for velocity distribution and pressure distributionof blood flow are obtained.Analysis for these formulas showsthat these formulas may be not only applied to the flow in theentrance region,but also applied to the flow in the region faraway from the entrance.A numerical example is presented to showthat the results in this paper are not only simpler and consistentwith the existent theoretical results,but also coinside well withthe experimental data.更多还原
