Energy management of compressed air systems. Assessing the production and use of compressed air in industry
(Corporación Universidad de la Costa, 2020)
The use of compressed air in industry is an important and yet overlooked energy carrier. Although there are different energy-saving measures discussed in the specialized literature, there is little discussion on the energy ...
Thermoeconomic evaluation and exergy efficiency of dissipative components: A new approach
(Journal of Engineering and Applied Sciences, 2018)
Thermoeconomic evaluation alms at diagnosing the malfunction of energy systems and at optimizing their structure and performance. One of the main limitations of this approach is the adequate treatment of dissipative ...
Combined method of flow-reduced dump load for frequency control of an autonomous micro-hydropower in ac microgrids
(Corporación Universidad de la Costa, 2021-12-02)
Nowadays, microgrids (MGs) play a crucial role in modern power systems due to possibility of integrating renewable energies into grid-connected or islanded power systems. The Load Frequency Control (LFC) is an issue of ...
The temperature gradient of cereals as an optimization parameter of the milling process in hammermills
(Corporación Universidad de la Costa, 2021-05-15)
The wear degree of knives in hammermills strongly influences electricity consumption, productivity, and total operating costs. Currently, the timely replacement of the knives set is decided based on visual inspections, a ...

The objectives of this study were to define and determine the energy efficiency indexes that should be considered to measure and analyze the energy performance in enterprises engaged in processing green coffee for export. ...
Experimental study of the potential for thermal energy recovery with thermoelectric devices in low displacement diesel engines
(Corporación Universidad de la Costa, 2021)
Improving the thermal efficiency of internal combustion engines is essential to reduce the operating costs and complaints with the increasing environmental requirements. Thermoelectric generators came up as an opportunity ...
Assessment criteria of the feasibility of replacement standard efficiency electric motors with high-efficiency motors
(Elsevier Ltd., 2021-08-26)
Currently, the feasibility to replace standard efficiency electric motors with higher efficiency ones is
assessed with considerations differing from real operating conditions in the industry. This study compares the ...
Induction motors with copper rotor: a new opportunity for increasing motor efficiency
(Institute of Advanced Engineering and Science (IAES), 2023)
The copper rotor induction motor (CURIM) was recently introduced because it has lower rotor fusion losses than the aluminum rotor (ALRIM). Furthermore, with CURIM, it is easier to reach IE4 and IE5 efficiency levels. The ...
