AbstractHierarchical relation between the deformation fields and vortical structures in a homogeneous isotropic turbulence is investigated. The stretching rates of the vortical structures are evaluated by replacing the extracted vortical structures by the vortex blobs. As a result, it is found that the individual vortices are likely to be stretched along the principal strain axes of flow field of larger scales.
