Experimental analysis of the behaviour of the droplets of high viscous fluids impacting on a flat heated surface

A lot of study speak about the behavior of water droplets, fuel droplets with particular references to burning and combustion processes, agricultural applications, heat transfer from heat surfaces. In this paper the behavior of droplets of high viscous fluid is analyzed to approach a new field of the application of the spray technology. In the last years, the development reached by propellers in terms of improvement of service and efficiency showed the problem of lubrication systems. A kinematics couples reaching high friction conditions, call for new solutions which allow the improvement of lubrication process[5], increasing transmission efficiency and lifetime of transmission. The aim of the present study is to develop a new system of lubrication where one or more injectors atomize lubricant previously filtered and send it in little drops on the surface of the transmission elements.
