TL;DR: In this paper, the authors present a review on the performance of Savonius wind turbines and present relevant information about their performance, bringing a discussion about the performance and benefits of using this type of turbines.

TL;DR: In this article, the numerical and experimental analysis of the turbulent flow of air inside a channel of rectangular section, containing two rectangular baffle plates, is presented, where the velocity field was measured with a hot wire anemometer, and the pressure field with an electronic manometer.

TL;DR: In this article, the velocity and temperature fields inside a tank submitted to internal natural and mixed convection were analyzed with two approaches: one using a two-dimensional model in cylindrical coordinates through the finite volume method and another using a one dimensional model.

TL;DR: In this paper, a numerical and an experimental analysis of velocity and temperature fields inside a storage tank submitted to natural convection is presented, where the analysis was performed in two stages, in the first stage the temperature profile along the vertical axis of the storage tank was obtained experimentally and numerically, for cooling time ranging from 45 to 60 h.

TL;DR: In this paper, a numerical simulation of the non-premixed combustion of natural gas in atmospheric air in an axis-symmetric cylindrical chamber is presented, focusing on the effect of thermal radiation on the temperature and chemical species concentration fields and the heat transfer.
