Development of a Cleaning Device using High-Speed Impinging Air Jet

Cleaning Efficiency – Which Efficiency? Study on the Influences of Nozzle Diameter, Pressure and Jet Moving Speed of Moving Impinging Jets

The cleaning of process equipment is a necessity in the pharmaceutical and food industry. Recently the efficiency of these cleaning processes comes more into focus due to the increasing economical and ecological demands. Except the ratio between benefit and efforts there is no consensual unique approach to assess the efficiency of cleaning processes so far. In this paper different assessment cr...

High-Fidelity Simulations of Primary Breakup and Impinging Jet Atomization

development of a 2-d numerical model for simulation of air distribution in high speed air water flow

in the present study a quasi 2-d numerical model is developed for calculating air concentration distribution in rapid flows. the model solves air continuity equation (convection diffusion equation) in the whole flow domain. this solution is then coupled with calculations of the free surface in which air content in the flow is also considered. to verify the model, its results are compared with a...

Heat Transfer of an Impinging Jet on a Plane Surface

Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...
