动力相似动力相似Dynamic similarity动力相似(dynamie simizarity)动力相似是指系统的对应部分承受着相似的净作用力的两个相似的流体流动系统之间的一种关系。绕几何相似物体的动力相似流动，其本身将会是几何相似的(见附图).因此，对于把模型试验结果有意义地用于外推全尺寸性能时，这个概念是基本的。但是，几何相似的流动不一定是动力相似的。—一仓二二尸二二二分~福二二二二二全至若簿蘸尽聋三聋三二二二笃之三三聋(a)馨绕过(a)冀剖面与(b)冀剖面〔与(的儿何相似」的动力相似流图如果两个流动系统的流动变量所组成的一定的无量纲参数具有相同的数值，则在它们之间会出现动力相似。建立动力相似流动的一个重要参数是压力系数P净俨，其中的户，p，和V分别是参考压力、密度和速度。其他的重要无量纲参数在下表中给出，该表还给出了表示这些参数特征的物理效应。下表中的参数可以通过量纲分析或者通过审查流动系统的微分方程与边界条件在长度、时间和质量的标量变换下的不变性来解析地确定。其他有用参数也可确定。这样一些参数常可由上表中的参数彼此相除来求得。动力相似参数 无t纲参卿川名称”杨理效应’户VL/产V/cVZ/乙gx./L户VZL/口e户产/‘夕TgL3产/产2雷诺数马赫数弗劳德数克努曾数韦伯数普朗特数格拉绍夫数粘性压缩性力力重压表面张力热传导自由对流l)参考变量规定如下:L，长度;产，粘性系数;。，声速;g，重力加速度;。，表面张力，‘，热传导系数，尹，热膨胀系数;T，温度;x二，分子平均自由程;‘，，定压比热在实际应用时，往往难于做到使两种流动的所有相似性参数同时都相等。通常使对应于起支配作用的流动特性参数相等就够了。例如，对低速粘性流动来说，两种流动的雷诺数应该相等，但马赫数可不考虑.参阅“童纲分析”(dimensional analysis)、“流体力学”(fluid meehanies)、“马赫数"(Maehnumber)条。
