Fluid flows between rotating concentric cylinders exhibit two distinct routes to turbulence. In flows dominated by inner-cylinder rotation, a sequence of linear instabilities leads to …

Recent experiments have reported a novel transition to elasto-inertial turbulence in the Taylor–Couette flow of a dilute polymer solution. Unlike previously reported transitions, this …
Pulsatile flow in a straight pipe is a model system for unsteady internal flows in industrial engineering and physiology. In some parameter regimes, the laminar flow is susceptible to …

We investigate the dynamics of a kerosene–water mixture in a vertical pipe flow by solving the Cahn–Hilliard–Navier–Stokes equations. We compute the linear stability of laminar core …

We present direct numerical simulations of the Taylor–Couette flow of a dilute polymer solution when only the inner cylinder rotates and the curvature of the system is moderate (η …
Despite its importance in cardiovascular diseases and engineering applications, turbulence in pulsatile pipe flow remains little comprehended. Important advances have been made in …

High-performance computing scientists are producing unprecedented volumes of data that take a long time to load for analysis. However, many analyses only require loading in the …
We show that, in the transitional regime of pulsatile pipe flow, at moderate-to-high amplitudes 0.5≲ A≲ 1, the first long-lived turbulent structures are localized and take the form …
Large-scale coherent structures are identified in turbulent pipe flow at $ Re_\tau= 181$ by having long lifetimes, living on large scales and travelling with a certain group velocity. A …
