Journal ArticleDOI
Boundary layer dynamics at the transition between the classical and the ultimate regime of Taylor-Couette flow
Rodolfo Ostilla-Mónico,Erwin P. van der Poel,Roberto Verzicco,Roberto Verzicco,Siegfried Grossmann,Detlef Lohse +5 more
TL;DR: In this paper, a simulation of turbulent Taylor-Couette flow is performed up to inner cylinder Reynolds numbers of Re i = 105 for a radius ratio of η = r i /r o = 0.714 between the inner and outer cylinders.
Journal ArticleDOI
A multiple-resolution strategy for Direct Numerical Simulation of scalar turbulence
TL;DR: A numerical procedure to simulate low diffusivity scalar turbulence is presented, the more advantageous the less diffusive the scalar is with respect to momentum, therefore it is particularly well suited for large Prandtl or Schmidt number flows.
Journal ArticleDOI
AFiD-GPU: A versatile Navier–Stokes solver for wall-bounded turbulent flows on GPU clusters
Xiaojue Zhu,Everett Phillips,Vamsi Spandan,John Donners,Gregory Ruetsch,Joshua Romero,Rodolfo Ostilla-Mónico,Rodolfo Ostilla-Mónico,Yantao Yang,Detlef Lohse,Roberto Verzicco,Massimiliano Fatica,Richard J. A. M. Stevens +12 more
TL;DR: The AFiD code, an open source solver for the incompressible Navier–Stokes equations, has been ported to GPU clusters to tackle large-scale wall-bounded turbulent flow simulations and the results are in excellent agreement with the experimental and computational data.
Journal ArticleDOI
Transition to geostrophic convection: the role of the boundary conditions
TL;DR: In this paper, the Navier-Stokes equations for two values of the thermal forcing were directly simulated, i.e., Ra=1010 and Ra=5×1010, at constant Prandtl number Pr=1, and vary the Ekman number in the range Ek=1.3×10−7 to Ek=2×10 −6, which satisfies both requirements of supercriticality and strong rotation.
Journal ArticleDOI
A parallel interaction potential approach coupled with the immersed boundary method for fully resolved simulations of deformable interfaces and membranes
Vamsi Spandan,Valentina Meschini,Rodolfo Ostilla-Mónico,Detlef Lohse,Detlef Lohse,Giorgio Querzoli,Marco D. de Tullio,Roberto Verzicco,Roberto Verzicco +8 more
TL;DR: This paper shows and discusses how the deformation dynamics of closed liquid–liquid interfaces (for example drops and bubbles) can be replicated with use of a phenomenological interaction potential model, and presents a simple and easy to implement parallelisation scheme.
