Understanding of the latter is essential for solving all major remaining problems in viscoelastic turbulence. Direct numerical simulation is used to study the transient growth of the laminar-turbulent edge state into full turbulence and comparison is made between Newtonian and viscoelastic fluid flows. Polymers are found to suppress turbulence growth throughout the process. Inspection of flow fields further reveals a different pattern of turbulence development after polymers are introduced.
