Low inertia limit of elasto-inertial turbulence
Shoaib Kamil, Sarath Sankar Suresh, Jose M. Lopez +1
Pipe and channel flows of viscoelastic fluids display chaotic dynamics at unusually low speeds, a phenomenon referred to as elasto-inertial turbulence, EIT. First reported in exper…
Experimental observation of the origin and structure of elasto-inertial turbulence
George H. Choueiri, Jose M. Lopez, Atul Varshney +2
Turbulence generally arises in shear flows if velocities and hence inertial forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit disordered motion e…
nsCouette -- A high-performance code for direct numerical simulations of turbulent Taylor-Couette flow
Jose Manuel Lopez, Daniel Feldmann, Markus Rampp +3
We present nsCouette, a highly scalable software tool to solve the Navier-Stokes equations for incompressible fluid flow between differentially heated and independently rotating, c…
Phase-field simulation of core-annular pipe flow
Baofang Song, Carlos Plana, Jose M. Lopez +1
Phase-field methods have long been used to model the flow of immiscible fluids. Their ability to naturally capture interface topological changes is widely recognized, but their acc…
Dynamics of viscoelastic pipe flow in the maximum drag reduction limit
Jose M. Lopez, George H. Choueiri, Bjoern Hof
Polymer additives can substantially reduce the drag of turbulent flows and the upper limit, the so called "maximum drag reduction" (MDR) asymptote is universal, i.e. independent of…
Boundary-layer turbulence in experiments of quasi-Keplerian flows
Jose M. Lopez, Marc Avila
Most flows in nature and engineering are turbulent because of their large velocities and spatial scales. Laboratory experiments of rotating quasi-Keplerian flows, for which the ang…
Conductive and convective heat transfer in fluid flows between differentially heated and rotating cylinders
Jose M. Lopez, Francisco Marques, Marc Avila
The flow of fluid confined between a heated rotating cylinder and a cooled stationary cylinder is a canonical experiment for the study of heat transfer in engineering. The theoreti…
The Boussinesq approximation in rapidly rotating flows
Jose M. Lopez, Francisco Marques, Marc Avila
In commonly used formulations of the Boussinesq approximation centrifugal buoyancy effects related to differential rotation, as well as strong vortices in the flow, are neglected.…
