... to exergy destruction (45%), followed by regeneration heater 1 (22%), desiccant wheel 1 (7%), and the heat recovery water heater (6%) during the critical operational month of August. Multi-objective optimization has also been conducted using the optimization toolbox provided in matlab -R2017a to determine...

... entrainment ratio at a specified spindle and primary nozzle exit position. A theoretical model using energy and exergy analysis illustrates the impact of hybrid systems on performance under different operating conditions (i.e., engine exhaust, ambient air, and evaporator temperatures). At a specified exhaust...

...K. Kiran Kumar; Banjara Kotresha; Kishan Naik The aim of this work is to unveil the exergy transfer and overall thermal performance of the metal foams partially filled in varying thicknesses in the vertical channel. The numerical examination performed in this study consists of a heater cum plate...

...Vikash Kumar; Rashmi Rekha Sahoo Technology innovation requires advanced heat transporting techniques to fulfill better exergy and economic behavior of compact air heat exchangers (HXs). Three different turbulator inserts, TTIs, PTTIs, and DTTIs (twisted turbulator inserts, perforated twisted...

... are optimized with the specific power consumption (SPC) as the objective function. The results show that the SPC of three cases are 0.8021 kWh/kg (LNG), 0.4150 kWh/kg (LNG), and 0.5063 kWh/kg (LNG); the coefficient of performance (COP) of cases 1, 2, and 3 are 0.20, 0.39, and 0.30; the exergy efficiency...

...Hirakh Jyoti Das; Pinakeswar Mahanta; Rituraj Saikia; Plabon Tamuly Effective thermodynamic analysis is quite necessary for proper system design performance and optimization of system processes. Energy is concerned with the quantitative evaluation of system processes. Nonetheless, exergy gives...

... on an existing 135 t/h combined heat and power plant (CHP). The results indicated that over the 50–70 °C exhaust temperature range of flue gas, the application of EHPE could obviously improve the energy efficiency and slightly promote the exergy efficiency. The energy and exergy efficiencies gradually increase...

...-phase refrigerant cooling was able to adjust to local hot-spots because of flow boiling’s dependency on the local heat flux, with junction temperatures being 20 to 30 °C lower when compared to water and the 50% water–ethylene glycol mixture, respectively. An exergy analysis was developed considering...
