Aiming for the better environmental and economic performance of traditional engines, waste heat recovery (WHR) technologies are actively studied to find their most beneficial applications. In this work, inverted Brayton cycle (IBC) is investigated as a potential WHR solution liquefied natural gas (LNG) fuelled transport truck. LNG being one less polluting fossil fuels widely spreading nowadays ...

This paper shows that any thermodynamic potential fulfilling some thermodynamic stability criterion (e.g. the chemical affinity or the ectropy) can be used as a potential function for the dissipative (pseudo) Port Hamiltonian formulation of the non isothermal Continuous Stirred Tank Reactor (CSTR) model. Besides Brayton-Moser formulation is used to obtain some dissipative Port Hamiltonian repre...

Printed circuit heat exchangers (PCHEs) have the characteristics of high temperature and pressure resistance, as well compact structure, so they are widely used in supercritical carbon dioxide (S-CO2) Brayton cycle. In order to fully study transfer process Z-type PCHE, a numerical model traditional PCHE was established accuracy verified. On this basis, new type spiral (S-ZPCHE) is proposed pape...

The supercritical carbon dioxide (sCO2) Brayton cycle is the preferred power for future nuclear energy, fossil solar and other energy systems. As regenerator in cycle, printed circuit heat exchanger (PCHE) exhibits a high transfer efficiency, compactness, robustness. structure design of its internal flow channel one most important factors to enhance reduce pressure loss. In present work, trapez...

This paper investigates the interest and potential of using working fluids based on Carbon Sulphur Dioxide mixtures (CO 2 -SO ) in a transcritical Recompression cycle. In order to assess actual thermodynamic concept proposed, influence dopant (SO content is assessed for two different turbine inlet temperatures (550 °C 700 °C). The results obtained are compared with other CO already proposed lit...

In today?s world, we are facing the problem of fossil fuel depletion along with its cost continuously increasing. Also, it is getting difficult to live in a pollution free environment. Solar energy one most abundantly and freely available form energy. Out various ways harness solar energy, thermal efficient as compared photovoltaic technology. There cycles convert mechanical work, but Kalina cy...
