Organic Rankine Cycle (ORC) is a suitable way to recover the waste heat of internal combustion engines. Since the engine usually operates under different working conditions, the waste heat recovery system is also under unstable state. Consequently, it is quite meaningful to research the dynamic behavior of the ORC. The dynamic math model of the ORC for waste heat recovery of a natural gas engine is...
The environment issue combined with the rising of crude oil price has attracted more attention in waste heat recovery of diesel engine. The Organic Rankine cycle (ORC) offers a good solution to utilize multi-grade waste heats of diesel engine. Conventional multi-source ORC systems are too complex for vehicle application. This paper proposed a two-stage expansion with interheating organic Rankine cycle...
Organic Rankine Cycle (ORC) is regarded as a very suitable method to recover the waste heat of internal combustion engines. Engines often operate under variable working conditions, so ORC systems are also under unstable state which means it is important to research the dynamic response. There are many kinds of working fluids and various dynamic response characters are reflected owing to their different...
The Enhanced Geothermal System (EGS) creates an artificial geothermal reservoir by hydraulic fracturing which allows heat transmission through the fractures by the circulating fluids as they extract heat from Hot Dry Rock (HDR). The technique involves complex thermal–hydraulic–mechanical (THM) coupling process. A numerical approach is presented in this paper to simulate and analyze the heat extraction...
