Development and operational optimization of microspray system

Construction of a novel liquid material micro dosing and spraying apparatus and its design optimization is presented in the paper. Its functionality is based on the influence of high frequency vibrations generated by cylindrical piezo-actuator to the flow of liquid substances in a micro tube. New models of the micro dosing elements are presented. Such spray systems provide high accuracy of micro dosing and are applicable in a variety of applications from avionics to medicine. Hybrid experimental-numerical analysis techniques are used for investigation of micro spray systems. Experimental analysis of the investigated systems is based on laser holographic interferometry which is used for the identification and optimization of working regimes of the system.
