Article dans une revue avec comité de lecture(American Physical Society, 2017)The generation of a turbulent inflow is a tricky problem. In the framework of aeroacoustics, another important constraint is that the numerical strategy used to reach a turbulent state induces a spurious noise which is ...

Article dans une revue avec comité de lecture(Springer Verlag, 2018)In this study the parabolized stability equations (PSE) are used to build reduced-order-models (ROMs) given in terms of frequency and time-domain transfer functions (TFs) for application in closed-loop control. The control ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2019)A restricted nonlinear (RNL) model, obtained by partitioning the state variables into streamwise-averaged quantities and superimposed perturbations, is used in order to track the exact coherent state in plane channel flow ...

Large eddy simulation of turbomachinery flows using a high-order implicit residual smoothing scheme Article dans une revue avec comité de lecture(Elsevier, 2020)A recently developed fourth-order accurate implicit residual smoothing scheme (IRS4) is investigated for the large eddy simulation of turbomachinery flows, characterized by moderate to high Reynolds numbers and subject to ...

Communication avec acte(American Institute of Aeronautics and Astronautics, 2017)We develop a reduced-order-model framework using the parabolized stability equations and identification techniques for the closed-loop control of unsteady fluctuations along fluidic systems. These models had been successfully ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2018)We investigate perturbations that maximize the gain of disturbance energy in a two-dimensional isolated vortex and a counter-rotating vortex pair. The optimization is carried out using the method of Lagrange multipliers. ...

Article dans une revue avec comité de lecture(SAGE Publications, 2015)The paper presents an analysis of the possibilities of exhaust gas heat recovery for a tractor engine with an output power of 110 kW. On the basis of a literature review, the Rankine cycle seems to be the most effective ...
