【 摘 要 】
References(12)Cited-By(20)Turbulent flow in a spray drying chamber was analysed experimentally. Instantaneous fluctuating velocity was measured by a hot-wire anemometer with a split-film probe. This measurement enabled us to obtain the correct velocity field in the chamber without atomization. The turbulent fluctuation in the spray drying chamber was extremely larger than the usual turbulent level of free jet or tube flow. It is suggested that the large fluctuation can be attributed to the unsteady nature of the downward jet, caused by the interaction between the shape of the chamber and the downward jet.
