The main emphasis is placed on numerical modelling of high speed water jet generation inside a circular nozzle and its outlet. The theoretical studies are performed based on the 3D geometry of nozzle received from the computed tomography. The models are experimentally verified by flow monitoring and visualization techniques. For the purpose of experimental testing, a closed water circuit was designed. The methods of Particle Tracking Velocimetry, Laser Induced Fluorescence and Shadowgraphy together with fluorescent seeding particles were applied for determination of jet velocity fields. A series of experiments was conducted to measure the flow conditions. Basic methods and principles used in the experiments are described in the paper. The results and analyses of the micro CWJs flow based on numerical modelling, visualization and monitoring show very good conformity of theoretical and practical tests.
