Context. High-resolution spectroscopy has revealed large concentrations of CNO and sometimes other intermediate-mass elements (e.g., Ne, Na, Mg, or Al, for ONe novae) in the shells ejected during nova outbursts, suggesting ...

A conservative approach for MPI-based parallelization of tridiagonal compact schemes is developed in the context of multi-block finite-volume methods. For each block, an enlarged linear system is solved by overlapping a ...

Direct numerical simulations of the incompressible Navier-Stokes equations are not feasible yet for most practical turbulent flows. Therefore, dynamically less complex mathematical formulations are necessary for coarse-grained ...

In this study are presented the numerical results obtained when simulating the abruptly stoppage of the outer cylinder in a Taylor-Couette system where the inner cylinder is static. The results are compared with the ...

In this work, a new model for the analysis of incompressible fluid flows with massive instabilities at different scales is presented. It relies on resolving all the instabilities at all scales without any additional model, ...

A simple approach to discretize the viscous dissipation term in the incompressible Navier–Stokes equations with spatially varying viscosity is presented. Unlike the case where the viscosity remains constant, its discretization ...

The resolution of the Navier Stokes equations in three dimensions in a turbulent regime applying turbulence models is studied. To accomplish this objective, it is done a brief introduction to the work done on the Final ...

This book includes a collection of chosen research papers from the partners of a research project (the Seventh Framework Programme Grant Agreement (Grant Number: 266326)) named Manipulation of Reynolds Stress for Separation ...

Heat island effect and air quality are major issues in big cities and the shape ofthe street canyons is directly related with these problems. The only presence the buildings modifies the temperature in their surroundings ...
