Exhaust Energy

The exhaust energy recovery is significant for engine fuel efficiency. However, the exhaust gas interference and the loss of flow affect the utilization of exhaust energy of multi cylinder turbocharged diesel engine seriously. In this paper, through Particle Image Velocimetry experiment and computational fluid dynamics simulation of exhaust T-junction flow field, the characteristics of junction local flow field and the law of energy loss are obtained. Based on the one dimensional simulation of engine working process, the exhaust available energy analysis is carried out, and the transmission of available energy of exhaust valve and various pipe systems under typical operating conditions is obtained. On this basis, five exhaust systems are designed, and the steady-state and transient performances are compared by bench tests. The results show that the shrinkage rate and the intersection angle of T-junction are the key factors affecting exhaust energy transmission and exhaust gas interference suppression. Reducing the branch pipe shrinkage rate leads to an increase in branch pipe flow loss, but it will also reduce the main pipe flow loss and exhaust gas interference. Reducing the angle between the main pipe and branch pipe is beneficial to the exhaust flow and exhaust energy recovery. The pulse converter exhaust system has a high exhaust available energy transmission rate; the Modular Pulse Converter system has superior fuel efficiency and transient response performance from the perspective of the entire engine operation range. The 90% response time difference between the five studied exhaust systems is about 0.41 s.

Flat grooved heat pipes, which are especially useful in obtaining a high degree of temperature uniformity on flat surfaces, have been successfully used in the temperature control of electronic systems, however, the mechanisms governing the flow and heat transfer of this kind of heat pipes are still under scrutiny as some reported results cannot be reproduced by others or some assumptions have been proven to be unreasonable or ideal. The theoretical and experimental studies on flat grooved heat pipes and introduce work performed on modeling flat grooved heat pipes are reviewed in this paper.
