The Eco-Energy Engineering course for students of Mechanical Engineering at Master level at AGH University of Science and Technology in Cracow is predominantly theoretical, with the additional computer-aided projects. In order to improve the quality of the course and make the learning process easier for students, some practical elements were introduced. One of them is the presented laboratory stand for the measurement and analysis of photovoltaic modules. The proposed platform consists of a photovoltaic module, rechargeable battery, variable load, charge controller, digital thermometer, solar radiation sensor, and measuring circuit. All the measured variables are stored on the SD card. Also, PC can be connected via the USB port. In order to make the teaching more dynamical, this stand was designed as mobile and it does not need an external power supply. A prototype of the stand was built and tested in real conditions during laboratory classes. A positive feedback from students showed the correctness of the proposed learning schedule and the didactic potential of the laboratory stand.
The publication presents the results of aerodynamic characteristics of selected profile blades for applications in wind turbines. Considering the potential of energy resources and investors’ preferences, the amount of energy produced in wind farms in the total amount of electricity generated will be systematically growing and probably, in the next few years, wind energy will be the first in the field of electricity production from all types of power plants. Harnessing the power of moving air masses is now a global phenomenon. Rotor wheel converts wind energy into mechanical energy when using blades with chosen shape and oriented in the terms of the optimum performance. The aim of the measurements was to determine the impact of blade shape and blade angle of attack on the efficiency of conversion of wind energy into mechanical energy on the rotor wheel. The obtained power coefficients were presented as results.
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.
