The aim of this study is to provide a coupled finite element–boundary element method approach for aeroelastic investigations in incompressible flow fields. Hence, an efficient and applicable tool for aeroelastic response computations is developed which uses boundary element method to solve flow fields and finite element method to analyze structural domains. In unsteady flow solution, the potential flow assumptions are considered, while the small deformations are assumed in structural dynamics behavior. Both solution procedures are tightly related by a boundary interface in a sequential coupling procedure. To illustrate the performance of aerodynamic solver for computation of three-dimensional unsteady flow configurations, lift response of a wing–body combination is computed and validated with available results in literature. Also, two test cases are presented that illustrate the accuracy of the developed tool for aeroelastic response analysis in comparison with available experimental results.
Daily increasing propagation of environmental pollutants, such as CO 2 as the most prevailing greenhouse gas, has resulted in global warming and climate changes in the past decades. Therefore, essentiality of the optimum utilization of limited sources of energy which in turn leads to emission abatement in energy conversion process is being widely under consideration. Cogeneration, regarding energy conservation and efficiency enhancement, is known to be a noticeable and overriding strategy in substantiation of energy consumption management goal. This study deals with performance evaluation of a microturbine-based cogeneration plant and its effects on efficiency and environmental aspects by using a simulator code.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
