The unstable gas stream is characterized by oscillations with transient velocities of about + 100 m / s and frequencies from 50 - 200h /. the enhanced mixing and transport processes lead to a highly efficient moisture evaporation rate during pulsating spray drying. the computational fluid dynamics ( cfd ) method was used for the analysis and investigation of flow, temperature and humidity fields in a pulsating flow spray - drying chamber
長期以來，對噴霧乾燥過程進行了各種試驗和模擬研究，但這些研究並不能揭示噴霧乾燥室內氣體運動狀態，顆粒群的運動軌跡和各種熱力學參數分佈信息，常規的測試手段又很難測得，而這些參數分佈信息對乾燥器沒計和過程優化具有重要指導作用。 -
On the basis of the primary studies upon the nonlinear interactions between the unstable waves and the self - excited oscillations in the flow, experiments were focused upon the attenuation effects on the oscillations of tripping wires, side jets and deflected plates, and upon the mechanisms for the attenuations
在對流動的不穩定波之間非線性相互作用過程和自激振蕩的基本規律研究的基礎上，實驗研究了絆線、旁射流和折板削弱自激振蕩的效果與機制。
