An experimental study of the dynamic response of a Newtonian fluid and a Maxwellian fluid under an oscillating pressure gradient is presented. Laser Doppler anemometry is used in order to determine the velocity of the fluid inside a cylindrical tube. In the case of the Newtonian fluid, the dissipative nature is observed. In the dynamic response of the Maxwellian fluid an enhancement at the frequencies predicted by theory is observed.
本文呈现了一项关于牛顿流体和麦克斯韦流体在振荡压力梯度下动态响应的实验研究。为了测定圆柱形管内流体的速度，使用了激光多普勒测速仪。在牛顿流体的情况下，观察到了其耗散特性。在麦克斯韦流体的动态响应中，观察到了在理论预测频率处的增强现象。
