By a News Reporter-Staff News Editor at Journal of Engineering -- New research on Wind Engineering is the subject of a report. According to news reporting originating from Ottawa, Canada, by VerticalNews correspondents, research stated, "The simulation of correlated non-uniform flowfields in the time domain is required for the study of many time-dependent aeroelastic phenomena. A novel method for achieving representative spatially- and temporally-correlated flow simulation for a moving point in space, such as a point on a helicopter rotor, is discussed herein."
Our news editors obtained a quote from the research from Carleton University, "This method uses the Fourier series to take frequency-domain information and from it reconstructs a time-domain velocity signal. It differs, however, from the traditional application in that the coefficients and phase angles for the Fourier components are modified at each time step to accommodate changing flowfield characteristics and achieve the correct correlations between one point in space and the next. This method is named the advancing Fourier series method."
According to the news editors, the research concluded: "This paper covers the specifics of the method, including its advantages and disadvantages relative to other correlated flow modelling techniques."
