Numerical method for strongly variable-density flows at low Mach number: flame-sheet regularisation and a mass-flux immersed boundary method
Matheus P. Severino, Fernando F. Fachini, Elmer M. Gennaro +2
A low-Mach-number flow, in the laminar regime, has intrinsically two characteristic spatial scales for a given time scale, or two characteristic temporal scales for a given spatial…
Counterflow around a cylinder
Matheus P. Severino, Leandro F. Souza, Elmer M. Gennaro +2
The incompressible flow around a circular cylinder, positioned at the center of an unconfined planar counterflow, is studied by means of numerical solutions of the conservation equ…
Fixed points of Personalized PageRank centrality: From irreducible to reducible networks
David Aleja, Julio Flores, Eva Primo +2
In this paper we analyze the PageRank of a complex network as a function of its personalization vector. By using this approach, a complete characterization of the existence and uni…
The impact of harmonic inflow variations on the size and dynamics of the separated flow over a bump
Himpu Marbona, Daniel Rodríguez, Alejandro Martínez-Cava +1
The separated flow over a wall-mounted bump geometry under harmonic oscillations of the inflow stream is investigated by direct numerical simulations. The bump geometry gives rise…
