Exergy analysis is a powerful and systematic tool for the improvement of energy systems, with many possible applications in both conversion and utilization of energy. Here we present selected applications, with a special attention to renewable energy systems (solar), covering both design and operation/control. After these applications to non-reactive systems, potential ways of reducing the larg...

This paper aims at studying a trigeneration system, based on an internal combustion engine and a steam ejector refrigeration system. The designed cycle is to generate cooling and heating energies, and supply power simultaneously. The cycle is studied from thermodynamics point of view and for this purpose, the first law of thermodynamics is applied to all components of the cycle. The efficiency ...

This research proposes the combination of a dual-loop non-organic Rankine cycle (DNORC) with an internal combustion engine to increase the output power of the recovery system by focusing on the increase in the energy input and system efficiency. In doing so, it investigates the strategy of increasing the mean effective temperature of heat addition in the high-temperature Rankine cycle (HTRC) (t...

In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...

Winter pruning has been a common practice in peach. Twig topping associated with it, but this used at the same intensity, regardless of cultivar. Therefore, study aimed evaluating productive behavior and quality ‘Maciel’ peach grafted on ‘Capdeboscq’ ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig intensities winter pruning. The following three evaluated: short ...

Thermodynamic analysis of a novel combined system which is combination of methane fired gas turbine cogeneration system (CGAM) with a supercritical CO2 recompression Brayton cycle (SCO2) and an Organic Rankine Cycle (ORC) is reported. Also, a comprehensive parametric study is performed to investigate the effects on the performance of the proposed system of some important parameters. Finally, a ...

Abstract Glulam-concrete composite floor (GCC) is a hybrid flooring system which adopted from timber-concrete (TCC) concrete by replacing the sawn timber joist to Glulam joist. The topping was poured on with stiffness connectors were installed prevent slip behaviour. engineered that has bigger strength compared swan timber. This study aims identify vibration behaviour of 7.6 m × 4.05 Concrete C...
