Tricritical Directed Percolation Controls the Laminar-Turbulent Transition in Pipes with Body Forces
Author(s): Guru K. Jayasingh and Nigel Goldenfeld
The laminar-turbulent transition in straight pipes is believed to occur through a continuous nonequilibrium phase transition in the directed percolation universality class. However, in curved pipes or in the presence of body forces it is possible to observe a discontinuous transition and other pheno… [Phys. Rev. Lett. 135, 104001] Published Wed Sep 03, 2025
