Název v původním jazyce

Investigation of Reynolds Stress in Fluid Flow

Popis výsledku v původním jazyce

In the case of pulsatile flow we are dealing with a complicated task taking in account a non-stationary character of the process. The change of flow characteristics is of fundamental importance for the solution of many technical problems. The investigation of pulsatile Newtonian fluid flow in circular rigid pipes is presented in the paper. The aim of the research was to deepen the knowledge of effect of model geometry and flow characteristics on Reynolds stress. Interesting results which were obtained will be used in practise. Velocity profiles were measured with a laser-Doppler anemometer. The assemble-average velocity profiles, fluctuating components of velocity and the Reynolds normal stress have been experimentally evaluated. One of the important features that accompany this type of fluid motion is the transition from laminar to turbulent flow. In our research we have focused on this factor and we tried to solve the dependence of the flow characteristics on dimensionless products.
