摘要

本文介绍了在带有偏心轴和Rushton涡轮机的搅拌槽中搅拌液体流量参数的实验测试结果。研究的重点是搅拌器轴相对于搅拌槽纵轴的位移对搅拌液体平均速度和液体湍流速度的影响，以及对槽内湍流强度的影响。所有实验都是在内径为286mm、底部有一个法兰的搅拌槽中进行的。轴偏心率的采用值为零（中心位置）和储罐半径的一半。使用激光多普勒风速计测量液体流动的瞬时速度。

Identification of the liquid turbulent flow based on experimental methods

This paper presents the results of experimental testing of parameters of the ﬂow of an agitated liquid in a stirred tank with an eccentri-cally positioned shaft and with a Rushton turbine. The investigations were focused on the impact of the stirrer shaft shift in relation to the stirred tank vertical axis on the agitated liquid mean velocities and the liquid turbulent velocity ﬂuctuations, as well as on the turbulence intensity in the tank. All the experiments were carried out in a stirred tank with the inner diameter of 286 mm and a ﬂat bottom. The adopted values of the shaft eccentricity were zero (central position) and half the tank radius. The liquid ﬂow instantaneous velocities were measured using laser Doppler anemometry.

期刊介绍： The aim of the Archives of Thermodynamics is to disseminate knowledge between scientists and engineers interested in thermodynamics and heat transfer and to provide a forum for original research conducted in Central and Eastern Europe, as well as all over the world. The journal encompass all aspect of the field, ranging from classical thermodynamics, through conduction heat transfer to thermodynamic aspects of multiphase flow. Both theoretical and applied contributions are welcome. Only original papers written in English are consider for publication.
