“…Natural gas is increasingly used as an alternative to petroleum fuels in internal combustion engines and industrial power plants [64][65][66][67][68] because of its smaller environmental effects compared to diesel and gasoline, 4,66,[69][70][71][72] as well as for economic reasons. 73 New combustion techniques 37,74 are related to the use of natural gas, as well as their control strategies.…”

The laminar flame speed plays an important role in spark-ignition engines, as well as in many other combustion applications, such as in designing burners and predicting explosions. For this reason, it has been object of extensive research. Analytical correlations that allow it to be calculated have been developed and are used in engine simulations. They are usually preferred to detailed chemical kinetic models for saving computational time. Therefore, an accurate as possible formulation for such expressions is needed for successful simulations. However, many previous empirical correlations have been based on a limited set of experimental measurements, which have been often carried out over a limited range of operating conditions. Thus, it can result in low accuracy and usability. In this study, measurements of laminar flame speeds obtained by several workers are collected, compared and critically analyzed with the aim to develop more accurate empirical correlations for laminar flame speeds as a function of equivalence ratio and unburned mixture temperature and pressure over a wide range of operating conditions, namely f = 0:6À1:7, p u = 1À50 atm and T u = 298À800 K. The purpose is to provide simple and workable expressions for modeling the laminar flame speed of practical fuels used in spark-ignition engines. Pure compounds, such as methane and propane and binary mixtures of methane/ethane and methane/propane, as well as more complex fuels including natural gas and gasoline, are considered. A comparison with available empirical correlations in the literature is also provided.

This article describes a hypothetical use in a micro solar plant of a small power tangential flow turbine prototype, built and tested at the Department of Mechanical, Energy and Management Engineering (DIMEG) of the University of Calabria. The turbine prototype has the ability to recover efficiently energy from small sources, better than other turbines of the same size, in a wide set of operating conditions and power operations, having the possibility to regulate the flow rate without excessive losses. The micro solar powered central unit is conceived with Parabolic Trough Collectors (PTCs): the vapor pressure analysis extends from 5 to 25 bar, while the inlet turbine temperatures considered are included in the range from 180 to 283 °C. Steam pressure at the turbine discharge has been set to 1 bar, simplifying so the plant complexity and making possible CHP generation. The solar field has been dimensioned, for each of the cases examined, in relation to the rated operating temperature and steam flow rate supplying the turbine. Finally, the last 25 bar configuration has been analyzed in more detail by extrapolating the annual energy output and the average efficiency of the overall cycle, also considering the cogeneration contribution.
