dc.description.abstractEn | The numerical simulations of supercritical fluids flows were always performed using finite volume methods. These methods were used in association with iterative schemes for coupling all the equations, leading to very time-consuming computational codes. In this paper, we propose a new algorithm for an uncoupled solution of energy and Navier-Stokes equations in the low Mach number approximation with a spectral method. Indeed, spectral methods are known to ensure the highest accuracy and to allow the use of very fast techniques, such as FFT and complete diagonalization of the operators, leading to very efficient computational codes. The algorithm proposed is evaluated on a problem of natural convection for which results obtained with a finite volume method are available in literature | |
