The most expensive part of the computations, the solutions of the fine-scale, are parametrized to be performed offline and store their results in dimensionless databases. This latter allows us to construct synthetic models to emulate the fine-scale behavior when global solutions are computed.<\/p>\n<p>In this talk, <strong>an introduction of the methodology is presented through the solution of the equations for scalar transport and homogeneous turbulent flows<\/strong>, and evaluated in some standard benchmarks where advantages over other numerical approaches are established. Also, the first attempts towards the application of the methodology to the treatment of multiphase turbulent flows are shown. Here, the turbulence modulation phenomenon is discussed and solutions obtained are compared with predictions from the bibliography.<\/p>\n<h5 class=\"cimne blue-background\" style=\"padding-left: 15px;float: none\">SPEAKER CV<\/h5>\n<p><strong>Juan Marcelo Gim&eacute;nez<\/strong><br \/>Informatics Engineering (2011), M.Sc. in Computation (2014) and Ph.D. in Engineering (2015, mention Computational Mechanics) by the Universidad Nacional del Litoral of Santa Fe, Argentina.
