2) 在深失速工况下,出现了大范围的流动分离和脱落涡现象,翼型升力急剧下降,POD和DMD方法得到的时变流场结构主频在70 Hz附近。在此工况下,流场发展出很多高频低能结构,由于结构细小而分散所以不易捕捉。相较于高频低能结构,低频高能结构更...
The jet case is employed to investigate mixing in a turbulent jet flow. In both cases, DMD and SPOD analysis are compared to test their performance concerning the analysis of complex flows and to highlight the complementarity between these two approaches....

PODDMDANNMachine learningThe aim of this work is to derive an accurate model of two-dimensional switched control heating system from data generated by a Finite Element solver. The nonintrusive approach should be able to capture both temperature fields, dynamics and the underlying switching control ...
As the POD method focuses on the energy of flow while the DMD method focuses on the frequency, the first two modes had many similarities, but the third and fourth modes demonstrated completely different vortex structures. The current researches play a role of preliminary investigations for further...
