Title:
An algebraic variational multiscale-multigrid method for large-eddy simulation: generalized-alpha time integration, Fourier analysis and application to turbulent flow past a square-section cylinder 
Abstract:
This article studies three aspects of the recently proposed algebraic variational multiscale-multigrid method for large-eddy simulation of turbulent flow. First, the method is integrated into a second-order-accurate generalized-α time-stepping scheme. Second, a Fourier analysis of a simplified model problem is performed to assess the impact of scale separation on the overall performance of the method. The analysis reveals that scale separation implemented by projective operators...    »
