Abstract:
This paper shows the possibility to use the energy of wind as an electrical powering solution to communities, which developed along mining activities. It has been analysed the intensity of the natural airflow established inside of a mine from Jiu Valley (Romania), which displays clear advantages in this matter, as the depression in altitude of the entrances of the mine is significant. A simple theoretical model was used and the values characterizing the air current were confirmed by the measurements done in the fields and by the simplified simulation in specialized computer software. A value of wind speed in the gallery of around 3.7 m /s was obtained by simulation which allows a wind turbine mounted at the mine opening to produce an energy of up to 770kWh. Modelling using Comsol Multiphysics software is a useful way to simulate wind flows in order to evaluate resources for the implementation of wind turbines, as less time consuming and cheaper than a measurement campaign. Such a numerical model developed using COMSOL Multiphysics 5.1. software, could be very efficient for the physics education.
