Temperature effect of impulsive motion in an air floatation nozzle

Abstract

This project examines the temperature effect of impulsive motion for an air floatation nozzle in three-dimensional using computation fluid dynamics approach. The nozzles were first modelled in two-dimensional and then extruded into three-dimensional. Some variations to the nozzle’s geometry were made in order to study the effects of various geometry setups such as variation in web distance, lip separation and adding holes along the side bar. The results indicate that non-linear relationship between the web distance and temperature distribution across the web. The results also show that the pressure decreases non-linearly as the web distance increases. The results for lip separation case studies also show non-linear relationship between the lip separation and the temperature distribution across the web. Finally, additional holes along the side bar produces more uniform temperature and pressure distribution on the web.
