In the development of a system-of-systems combat simulation, how to design the architecture of the combat system-of-systems model determines if the final simulation result is satisfying or not. Here, a fresh network-centric architecture is put forward to support the modeling and simulation for combat system-of-systems. This architecture takes the communications network model as the basis platform,...
In order to analyze the characteristics of the transcritical CO2 heat pump system with throttle valve, it is necessary to simulate and further to optimize control the system operation. Therefore, the mathematical model for this system is developed in this paper. The simulation values are validated by the test data. The results show that the average error for cooling coefficient of performance (COP)...
The purpose of this study is to investigate the mixture formation processes of a third-generation spray (TGCS), an impinging spray that is intended to be applied in mixture preparation for homogeneous charge compression ignition (HCCI) diesel combustion. The spray visualization is performed in a constant-volume vessel by high-speed photography, to investigate the characteristics of the TGCS, and also...
In order to optimize and control transcritical CO2 refrigeration cycle, a mathematical model was developed to simulate the system performance. The simulation results show that a maximum COP exists at the optimal heat rejection pressure not only for throttle valve cycle but also for expander cycle. Also, the optimal heat rejection pressures of the throttle valve cycle are greater than those of the...
