Special Issue Information

Dear Colleagues,

The high-quality development of society and the economy is inseparable from various types of energy, which are based on different chemical systems and reactions. Oil and gas development, fuel combustion, fuel cell and other forms of energy are utilized by chemical reactions and heat release. Deep investigations on the thermodynamics of chemical systems will be fundamental in future. Thermodynamic study is a key basis of the understanding and use of different kinds of energy before its commercial application.

This Special Issue aims to further develop thermodynamic theory in chemical systems that are relevant to energy use, and tries to establish more advanced methods, techniques and models for high-efficient energy conversion. We encourage the submission of various forms of thermodynamic research on the development, utilization and storage of any form of energy, such as determining the temperature response mechanism, conducting thermophysical property measurements, building a thermodynamic theory model, and making thermodynamic relation predictions. Papers on experimental, model and theory analyses are all acceptable.

In this paper, a waste heat recovery compound system for series hybrid electric vehicles is established. The existing components of vehicle air conditioning are used in the organic Rankine cycle (ORC) to realize miniaturization. The waste heat recovery compound system is constructed using GT-SUITE, and the objective of the analysis is to increase the power output and engine thermal efficiency increase ratio (ETEIR). The effects of the expander speed, pump speed, working fluid mass flow rate, and working fluid type on the waste heat recovery compound system are analyzed. The simulation results show that the optimal schemes for the ORC system and compound system corresponding to the expander speed and pump speed are 1000 pm, 2500 rpm, 1200 rpm, and 2500 rpm, respectively. Compared with the ORC system, the maximum power output of the compound system with the same working fluid in three states (1500 rpm, 2500 rpm, and 3500 rpm) of the engine is increased by 21.67%, 24.05%, and 28.23%, respectively. Working fluid supplies of 0.4 kg/s, 0.4 kg/s, and 0.6 kg/s in the three engine states are also considered the best solutions. The working fluid R1234yf and R1234ze are the preferred choices for a waste heat recovery compound system, which have a high system power output and ETEIR and are environmentally friendly.
