Abstract

Guest editorial Guest editorial: turbulent flows in aerodynamics applications This special issue of the International Journal of Numerical Methods for Heat and Fluid Flow focuses on turbulent flows in aerodynamics applications. Turbulent flow regimes, compressible or otherwise, are omnipresent in high-Reynolds- number aerodynamic systems. Accurate prediction is required to anticipate and optimise the performance of new concepts. Optimisation is particularly important where the reduction of chemical and noise pollution is concerned. Robustness and safety for real weather and varying environmental conditions is also critical for aeronautical/terrestrial transportation and for renewable-energy industries. These constraints have driven significant progress in the academic and industrial communities in recent years, for instance in the fields of hybrid, large-Eddy simulation and Lattice–Boltzmann approaches for the modelling and analysis of unsteady industrial flows; or in the development of measurement methodologies that are now frequently used in the context of data-driven modelling. New theoretical frameworks have appeared for the description of out-of-equilibrium turbulence, and for the reduction and modelling of coherent structures and their sound radiation.
