Journal ArticleDOI
Numerical investigation of the effect of two-stage injection strategy on combustion and emission characteristics of a diesel engine
TL;DR: In this article, the effects of the two-stage injection interval and the first-stage fuel injection proportion on the combustion and emission characteristics when employing these two injection strategies were investigated by numerical modeling, dividing the in-cylinder zone into three different regions.
Journal ArticleDOI
Operation performance comparison of CCHP systems with cascade waste heat recovery systems by simulation and operation optimisation
TL;DR: In this article, the authors investigated the operation performance of the waste heat recovery system (WHRS) with the entire CCHP system to reveal its effects on the system efficiency.
Proceedings ArticleDOI
Theoretical Analysis of a Combined Thermoelectric Generator (TEG) and Dual-loop Organic Rankine Cycle (DORC) System Using for Engines' Exhaust Waste Heat Recovery
TL;DR: In this paper, the authors presented a model system TEG-DORC that employs thermoelectric generator (TEG) as a topping cycle integrated with a dual-loop organic Rankine bottoming cycle to recover exhaust heat of internal combustion engine (ICE).
Journal ArticleDOI
The investigation of the Recuperative Organic Rankine Cycle models for the waste heat recovery on vehicles
TL;DR: In this article, a Basic ORC (BORC) model and three RORC models with different recuperative rate were combined with engine model and compared, and the results showed that exhaust mass flowrate is mainly responsible for the engine backpressure variation.
Journal ArticleDOI
Numerical analysis of forced convection of high-temperature exhaust gas around a metal-foam wrapped cylinder
TL;DR: In this paper, a macroscopic model using the Darcy-Forchheimer-Brinkman momentum equation and the local thermal non-equilibrium energy equation has been established to simulate the forced convection around a metal foam-wrapped tube, and the heat transfer and pressure drop performance are investigated.
