On the role of inertia and self-sustaining mechanism in two-dimensional elasto-inertial turbulence
Haotian Cheng, Hongna Zhang, Wenhua Zhang +3
Elasto-inertial turbulence (EIT) is primarily driven by polymer elasticity, yet the modulating role of fluid inertia is non-negligible and remains largely unexplored. To investigat…
Anomalous Reynolds stress and dynamic mechanisms in two-dimensional elasto-inertial turbulence of viscoelastic channel flow
Haotian Cheng, Hongna Zhang, Wenhua Zhang +4
Elasto-inertial turbulence (EIT) has been demonstrated to be able to sustain in two-dimensional (2D) channel flow; however the systematic investigations on 2D EIT remain scare. Thi…
The minimal flow unit and origin of two-dimensional elasto-inertial turbulence
Zhang Hongna, Cheng Haitian, Wang Suming +3
The research on elasto-inertial turbulence (EIT), a new type of turbulent flow, has reached the stage of identifying the minimal flow unit (MFU). On this issue, direct numerical si…
Re-picturing viscoelastic drag-reducing turbulence by introducing dynamics of elasto-inertial turbulence
Zhang Wen-Hua, Zhang Hong-Na, Li Yu-Ke +1
Recently, the nature of viscoelastic drag-reducing turbulence (DRT), especially maximum drag reduction (MDR) state, has become a focus of controversy. It has long been regarded as…
Role of elasto-inertial turbulence in viscoelastic drag-reducing turbulence
Zhang Wenhua, Zhang Hongna, Yuke Li +2
Two kinds of nonlinearities coexist in viscoelastic fluid flows, i.e., inertia and elasticity, which can engender different types of chaotic states including IT, DRT, ET and EIT. T…
