Modal and Probabilistic Analysis of Wind Turbine Blade under Air-FlowIJERA Editor
Wind power is one of the most important sources of renewable energy. Wind-turbines extract kinetic energy from the wind and convert it into mechanical energy. Therefore wind turbine power production depends on the interaction between the blade and the wind. The fluid-structure interaction, that means the interaction of some deformable structure with a surrounding or internal fluid flow, belong nowadays to the most important and challenging multi-physics problems which are aimed to treat by numerical simulations. The topic fluid-structure interaction plays a dominant role in many fields of engineering. Therefore, a strong need for appropriate numerical simulation tools exists with a variety of numerical and physical aspects. The present paper takes care about fluid-structure interaction using modern simulation techniques such as coupled field analysis. This work illustrates the use of load transfer coupled physics analysis to solve a steady-state air flow-blade interaction problem, followed by modal analysis where natural frequency are obtained with two different approaches: deterministic and probabilistic. The numerical results are deduced from a finite element approximation of the coupled problem with a non-symmetric pressure/displacement formulation. Deterministic and probabilistic results are given and discussed.

ROMPECABEZAS DE ECUACIONES DE PRIMER GRADO OLIMPIADA DE PARÍS 2024. Por JAVIE...JAVIER SOLIS NOYOLA
El Mtro. JAVIER SOLIS NOYOLA crea y desarrolla el “ROMPECABEZAS DE ECUACIONES DE 1ER. GRADO OLIMPIADA DE PARÍS 2024”. Esta actividad de aprendizaje propone retos de cálculo algebraico mediante ecuaciones de 1er. grado, y viso-espacialidad, lo cual dará la oportunidad de formar un rompecabezas. La intención didáctica de esta actividad de aprendizaje es, promover los pensamientos lógicos (convergente) y creativo (divergente o lateral), mediante modelos mentales de: atención, memoria, imaginación, percepción (Geométrica y conceptual), perspicacia, inferencia, viso-espacialidad. Esta actividad de aprendizaje es de enfoques lúdico y transversal, ya que integra diversas áreas del conocimiento, entre ellas: matemático, artístico, lenguaje, historia, y las neurociencias.
