    Article
    Restricted access - publisher's policy
    The Sparse Matrix Vector Product (SpMV) is one of the main operations of iterative solvers, and, in a parallel context, it is also the siege of point-to-point communications between the neighboring MPI processes. The ...
  • Heat Transfer Effects on a Fully Premixed Methane Impinging Flame 

    Mira, Daniel; Zavala, Miguel; Avila, Matías; Owen, Herbert; Cajas García, Juan Carlos; Vázquez, Mariano; Houzeaux, Guillaume (Springer, 2016-01-09)
    Article
    Open Access
    A numerical assessment of different thermal conditions for an impinging flame configuration is investigated using large-eddy simulation. The cases of study correspond to a turbulent methane flame at equivalence ratio ER = ...
