Multilayer modelling of ozone fluxes on winter wheat reveals large deposition on wet senescing leaves
Understanding how ozone is deposited on vegetation canopies is needed to perform tropospheric greenhouse gas budgets and evaluate the associated damage on vegetation. In this study, we propose a new multilayer scheme of ozone deposition on vegetation canopies that predicts stomatal, cuticular and soil deposition pathways separately. This mechanistic ozone deposition scheme is based on the multi-layer, multi-leaf mass and energy transfer model MuSICA. This model was chosen because it explicitly simulates the processes of rain interception, through fall and evaporation at different depths within the vegetation canopy, so that ozone deposition on wet leaf cuticles can be explicitly modelled wi…
Numerical investigation of boundary layer detachment by active flow control
International audience; After decades of investigations have failed to produce a positive outcome on flow control technologies that requires complex devices and micro-plumbing, recent technologies like synthetic jets, DBD (Dielectric Barrier Discharge) seems to be promising and these technologies can overcome limitations of the old ones. Our work mainly deals with delaying boundary layer detachment of over an aerodynamic body (Air foil). In this paper we produce our study of an active flow control device over the BL detachment point over a circular cylinder by the aid of simulations. Results from the uncontrolled flow seem to be in accordance with literature and the presence of the jet has …
