The contributions to the Corfu symposium were published as "Advances in Hybrid RANS-LES Modelling" (NNFM, Vol. 97). At the Gdansk symposium, along with four invited keynotes, another 28 papers were presented addressing topics on Unsteady RANS, LES, Improved DES Methods, Hybrid RANS-LES Methods, DES vs. URANS and other Hybrid Methods, Modelling-related Numerical Issues and Industrial Applications. Additionally, a comprehensive summary of a round-table discussion on hybrid RANS-LES methods is presented. The present book reflects recent activities and new progress in the development and applications of DES and other hybrid RANS-LES modelling approaches to handle both industrial and fundamental flow problems Bibliography Includes bibliographical references and author index Notes English Print version record Subject Turbulence -- Mathematical models -- Congresses Eddies -- Mathematical models -- Congresses Reynolds stress -- Mathematical models -- Congresses Hydraulic engineering.
