Thermal effect in pressure fluctuation : internal flow

Abstract

In industrial processes, turbulent flows are known to sometimes generate significant levels of noise and consequent vibrations of the structures. As well the involvement of the heat in the most engineering processes; this study focus on the effect of temperature of the internal flow in the tube has been investigated numerically to study the vibration tendency on the tube structure. The Fluent software has been used with LES solution provided for more accurate results. The results show the direct relation of the temperature in the vibration tendency. The results also show that the diameter of the tube has inverse relationship to the vibration tendency of the structure.
