Detailed analysis of POD method applied on turbulent flow

Original language description

Proper orthogonal decomposition (POD) on very turbulent flow inside the street canyon is performed. The energy contribution of each mode is yielded up. Also, physical meaning of the POD method is clarified. Particular modes of POD are assigned to the particular flow events like sweep event, vortex behind the roof or vor- tex at the bottom of street. Test of POD sensitivity on the length of data recording is done when the acquisition time increases up to its triple value. Test with decreasing sample frequency is executed. Further, interpola- tion of POD expansion coefficient is attempted in order to test possible increase in sample frequency and get new information about flow from the POD analysis. We tested linear and spline sort of interpolation and the linear one brought slightly better results.
