Yet we are quite far from the complexity of microscopic molecular physics, since we only deal with Newtonian mechanics laws applied to a continuum, in which the effect of molecular fluctuations has been smoothed out and is represented by molecular-viscosity coefficients. Such a system has a dual behaviour of determinism in the Laplacian sense, and extreme sensitivity to initial conditions because of its very strong non linear character. One does not know, for instance, how to predict the critical Reynolds number of transition to turbulence in a pipe, nor how to compute precisely the drag of a car or an aircraft, even with today‘s largest computers. 1 We know, since the meteorologist Richardson, numerical schemes allow ing us to solve in a deterministic manner the equations of motion, starting with a given initial state and with prescribed boundary conditions. They are based on moment um and energy balances. However, such aresolution requires formidable computing power, and is only possible for low Reynolds numbers. These Direct-Numerical Simulations may involve calculating the | | 出版日期 | Book 20011st edition | | 关键词 | Extension; Incompressible Fluids; Large Eddy Simulation; Scale Separation; computational fluid dynamics; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-662-04416-2 | | isbn_ebook | 978-3-662-04416-2Series ISSN 1434-8322 Series E-ISSN 2198-2589 | | issn_series | 1434-8322 | | copyright | Springer-Verlag Berlin Heidelberg 2001 |
