DESCRIPTION:Tristan Revaz (WIRE\, EPFL)\nAbstract: Wind turbine flows ar
 e highly sensitive to the base flow details\, making them strongly influen
 ced by topography\, atmospheric conditions\, and upstream turbines. While 
 most studies focus on the base flow impact on the turbine wake flow and po
 wer output\, few address its impact on the turbine power efficiency. Using
  large-eddy simulations\, this work explores this relationship and demonst
 rates that the base flow can modify the turbine efficiency by up to 20%. C
 lear relationships are identified between the power coefficient\, inductio
 n factor\, wake deficit\, and base flow characteristics. Some of these rel
 ationships can serve as a predictive tool for assessing turbine power effi
 ciency. A key result is the strong connection between the turbine power ef
 ficiency and the wake development\, which helps to explain the observed ef
 fects.The results suggest that the base flow influences the wake\, which i
 n turn affects the flow through the turbine\, and thus modify the turbine 
 power efficiency. In this context\, an analytical model is developed to co
 mpute the effect of base flow pressure gradients on the turbine induction 
 and power efficiency.\n\nBio: Tristan is PhD student at the Wind Engineer
 ing and Renewable Energy Laboratory (WiRE) at EPFL. His research focuses o
 n large eddy simulation of wind turbine flows and the interaction between 
 wind turbine wakes and turbine power efficiency. He holds a BS and MS in M
 echanical Engineering from EPFL\, with a specialization in Fluid Mechanics
  and a minor in Computational Science and Engineering. During his master p
 roject at Enercon\, he investigated the application of large eddy simulati
 ons for wind resource assessment in complex terrain. Following this\, he w
 orked as a consultant with MeteoTest on a project using large eddy simulat
 ions to model air flow and heat distribution in the Lucerne region.
