Webexceeds a critical threshold. This phenomenon is known as the coil{stretch transition [1] and is observed in both laminar [2, 3] and random ows [4{6], even though with partially di erent features in the two cases. Several observables have been used to characterize the coil{stretch transition. A natural quantity is the steady-state distribution of WebAug 24, 2024 · The coil-stretch transition and the tumbling instability are characterized as a function of three parameters: the Péclet number, the Stokes number, and the chain length. Numerical results show that the coil-stretch transition remains when inertia is present and that it depends nonlinearly on the Stokes and Péclet numbers. Theoretical and ...
