Raniero SanninoIn the context of the great research pulse on clean energy transition, distributed energy systems have a key role, especially in the case of integration of both renewable and traditional energy sources. The stable interest in small-scale gas turbines can further increase owing to their flexibility in both operation and fuel supply. Since their not-excellent electrical efficiency, research activities on micro gas turbine (MGT) are focused on the performance improvements that are achievable in several ways, like modifying the Brayton cycle, integrating two or more plants, using cleaner fuels. Hence, during the last decades, the growing interest in MGT-based energy systems encouraged the development of many numerical approaches aimed to provide a reliable and effective prediction of the energy systems’ behavior. Indeed, numerical modeling can help to individuate potentialities and issues of each enhanced layout or hybrid energy system, and this review aims to discuss the various layout solutions proposed by researchers, with particular attention to recent publications, highlighting the adopted modeling approaches and methods.

The combustion efficiency and the gaseous emission of a 100 kWe MGT, designed for working with natural gas but fuelled with blends containing up to 10% of hydrogen is investigated. A critical comparison between experimental data and results of the CFD analysis of the combustor is discussed. The k-epsilon RANS turbulence model and the Finite Rate – Eddy Dissipation combustion model were used in the numerical computations. The chemical kinetic mechanisms embedded were the 2-step Westbrook and Dryer for methane oxidation, 1-step Westbrook and Dryer for hydrogen oxidation and the Zeldovich mechanism for NO formation. The experimental data and numerical computations are in agreement within the experimental accuracy for NO emissions. Regarding CO, there is a significant deviation between experimental and computational data due to the scarce predictive capability of the simple two steps kinetic mechanism was adopted. From a practical point of view, the possibility of using fuels with a similar Wobbe index was confirmed. In particular the addiction of 10 % of hydrogen to pure methane doesn’t affect the behavior of the micro gas turbine either in terms of NO or CO emissions.
Journal Article
Fabrizio RealeIn recent years supercritical CO2 power plants have seen a growing interest in a wide range of applications (e.g., nuclear, waste heat recovery, solar concentrating plants). The Allam Cycle, also known as the Allam-Fetvedt or NET Power cycle, seems to be one of the most interesting direct-fired sCO2 cycles. It is a semi-closed loop, high-pressure, low-pressure ratio, recuperated, direct-fired with oxy-combustion, trans-critical Brayton cycle. Numerical simulations play a key role in the study of this novel cycle. For this reason, the aim of this review is to offer the reader a wide array of modeling solutions, emphasizing the ones most frequently employed and endeavoring to provide guidance on which choices seem to be deemed most appropriate. Furthermore, the review also focuses on the system’s performance and on the opportunities related to the integration of the Allam cycle with a series of processes, e.g., cold energy storage, LNG regasification, biomass or coal gasification, and ammonia production.
About Me
Fabrizio Reale was born in Naples, Italy, in 1978. He got his "Laurea" degree (M.Sc.) in Mechanical Engineering in 2003 and in 2007, he earned his Ph.D. in Mechanical Systems Engineering, both from the University of Naples Federico II. Between 2007 and 2008, he served as a postdoctoral fellow at the University of Naples. From 2008 to 2012, he continued his postdoctoral work at the Istituto Motori of CNR in Naples.
Since 2012, he has been a researcher at the CNR, working at the Institute of Sciences and Technologies for Sustainable Energy and Mobility - STEMS (formerly Istituto Motori).
From 2019 to 2021, he was chair of the IGTI ASME TURBO EXPO Microturbines, Turbochargers & Small Turbomachines committee, for which he previously served as the vanguard chair (2017-2019).
Currently he serves as an expert evaluator for the Italian Ministry of Enterprises and Made in Italy assessing project proposals on energy and mobility. He has been peer reviewer for prominent journals within his research field and he is within the reviewer board of the 3.2 IF journal Energies. He is the head of research unit for the project Bio-FIRed IC Engines for off-grid Electric VEhicles ChaRging Stations, funded under the framework of the Italian Research Projects of National Interest (PRIN).
His current primary research areas include numerical modelling of WHR and integrated energy systems based on gas turbines, ORC, sCO2 gas turbines and of MGTs fuelled with biofuels or hydrogen-methane blends.
