Exact Solutions for Modified Burgers Vortex
نویسنده
چکیده
The vortex stretching process is relevant to energy transport at various scales in turbulent flow and in vortex reconnection. For these, reasons, exact solutions for vortex flow are useful. Robinson and Saffman [1] examined the Burgers vortex solution and found closed form steady solutions for special parameter values. Unsteady 2D Burgers vortex solutions have been used to model the spanwise structure of turbulent mixing layers (Lin and Corcos [2], Neu [3]). Unsteady axisymmetric Burgers vortex solutions are used in modeling the fine-scale structure of homogeneous incompressible turbulence (Townsend [4], Lundgren [5]).
