Abstract
A simple clipping procedure based on Taylor series approximation was suggested to improve the stability of LES computations using the dynamic mixed model (DMM). The clipping procedure derived from a rigorous mathematical analysis uses terms which are anyway determined in the DMM model and thus, does not require additional calculations. The effect of the clipping was tested by calculations of turbulent mixing in a coaxial jet mixer. The suggested procedure has potential to be extended to LES of complex‐geometry turbulent flows.
