Chudanov, A. Aksenova, V. Pervichko, A. Makarevich] A three-dimensional CFD code CONV-3D is being developed for mathematical modeling of the fluid dynamics of elements of nuclear power facilities. The code is based on developed algorithms with low artificial diffusion, for which discrete approximations are constructed using finite-volume and staggered grid methods. A regularized nonlinear monotonic operator splitting scheme has been developed to solve advection problems. Richardson's iteration method with a fast Fourier transform for the Laplace operator is used to solve the pressure equation. Compared with the conventional conjugate gradient method this approach to the solution of elliptic equations with variable coefficients gives multiple acceleration. Quasi-direct numerical modeling is used to model three-dimensional turbulent flows in single-phase streams. The CONV-3D code is completely parallelized and is effective on multiprocessor cluster computers, such as Chebyshev and Lomonosov (MGU). Springer Science+Business Media New York, 2015 Chudanov V.
