This thesis is dealing with cleaning of pharmaceutical vessels with the use of static spray balls. Appropriate use of spray ball geometry and process parameters can significantly impact cost and environmental impact of cleaning. Using an experimental station, we analyze the flow characteristic of the spray ball, the trajectory of the jet and the collision of the jet against the wall of the vessel. We set up a model to calculate the trajectory of the jet generated in the spray ball, depending on the geometry of the spray ball and the process parameters. We measured the size of the wetted surface at the collision of the jet against the wall of the vessel, depending on the geometry of the spray ball and the process parameters.
