Abstract. The article is devoted to the domestic waste recycling challenges in our country and possible ways to address them. Today, these issues are considered to be multifaceted and involve not only the enterprises but also the corresponding authorities and the population itself. The experience of the developed countries proves that the use of progressive innovative technologies in waste managing can solve a number of problems in the field of economy, ecology and public health. To implement such technologies a coherent action of all participants in the waste management process is required. The authorities and enterprises should be clearly coordinated in addressing the challenges of the development and implementation of lowwaste technologies. Moreover, it is necessary to raise the level of environmental knowledge among the population.

“…The compressor studied in this work has been developed by DIME in a research project related to the multidisciplinary optimization of several components of a MGT. The preliminary geometry, obtained by employing a classical one-dimensional and then two-dimensional design procedures [8], has been optimized by using an artificial neural network coupled with a genetic algorithm with the purpose of minimizing an objective function linked to aerodynamics losses and mechanical stresses; the results of this work are widely presented in [9] and [10]. In the following, the main characteristics of the compressor are summarized.…”

The aim of this paper is to investigate the design in similarity of a centrifugal compressor for micro gas turbine and the related scaling effects on performance using CFD investigations. This work is part of a research project carried out by the Department DIME of the University of Genova, with the purpose of investigating the performance of a micro gas turbine in the change from 100 kW electrical output to 250 kW, while maintaining the compressor pressure ratio and geometry in similarity. The first part of the work focuses on the comparison between the original and the scaled machine, while the second part of the study deeply investigates the tip gap effect in the new configuration. The aim is to provide information about the performance of the compressor designed in geometrical similarity and to evaluate the tip gap height impact. From the efficiency point of view, the scaled-up machine has higher efficiency (up to 1.4% increment in design conditions) keeping the same technological limit for impeller manufacturing. However, the variation of tip gap height in the range 0 ÷ 1 mm strongly affects this parameter, leading to 10% alteration in design conditions between the ideal and worst case. The results, both in terms of overall performance and flow fields, are widely discussed in order to obtain simple yet reliable correlation for preliminary design.

“…For radial turbine, the aim of the objective function is to drive the optimization process to ensure a mass flow rate equal to design condition, to keep the outlet tangential velocity in a desired range along spanwise direction (sampling the values on four spanwise sections), and to maximize the overall efficiency. The optimization procedure above described has been employed to obtain the optimal geometries for both centrifugal compressor and radial turbine for the case with cycle pressure ratio of 4.5, as extensively reported in [28], [29] and [30]. The case relating to a pressure ratio of 6 it is currently being optimized, following the same procedure previously presented.…”

The objective of energy production with low environmental impact will have, in the near future, high potential of development also for naval applications. The containment of pollutant emissions can be achieved by the combined use of an innovative mini gas-steam combined cycle with thermal energy cogeneration to feed the ship thermal utilities, in place of the current Diesel engine application, and liquefied natural gas as fuel (LNG). The present work is focused on the definition of the architecture of the plant, by selecting optimal distribution of pressure and temperature and repartition of power between Gas Turbine (GT), Steam Turbine (ST) and thermal utilities, as well as on the choice and sizing of the individual components. The main purpose is the definition of a compact, high efficiency, system. The proposed basic mini-cycle ranges from 2 MW to 10 MW electric power. Thanks to the combined heat and power cogeneration plant adopted, for an overall electrical efficiency of about 30%, a total return (thermal + electricity) of about 75% can be achieved. An example of plant providing large power, in a partially modular arrangement is also proposed.
