The improvement of the overall utilization rate compressed natural gas (CNG) engine fuel is basis efficient energy utilization. On foundation heat balance theory internal combustion engines, this study fully considers operation characteristics CNG engines and systematically analyzes distribution different waste under variable working conditions. nonlinear relationship between speed intercooler ...

Multistage type cold storage is a refrigeration machine required in an industry because it functions to store food products for long time. Bali, as world tourist destination, will rely heavily on this cooling system preparing services tourists, especially the and beverage sector. designed reach evaporator temperature below -30oC thus used compressor performance must be able produce maximum effe...

The investigation of the various heat management concepts using LH2 requires development a modeling environment coupling cryogenic hydrogen fuel system with turbofan performance. This paper presents numerical framework to model hydrogen-fueled gas turbine engines dedicated heat-management system, complemented by an introductory analysis impact precool and intercool in compression system. propul...

Pollution emission levels of aircraft engines are a nowadays high concern. Any technological advance that could reduce emission levels is always welcome. In what concerns aircraft engines, a possible solution for this problem could be the use of regenerators and intercoolers. These components might reduce the specific fuel consumption, increase efficiency and specific thrust and consequently re...

A computer model representing a two-evaporator, two-intercooler refrigerator-freezer opera ting at steady-state with nonazeotropic refrigerant mixtures (CYCLEZ) has been developed at Oak Ridge National Laboratory (ORNL). This model is being used to assess the effects of system desig n and operating parameters on the cycle performance of a refrigerator-freezer designed around the L orenzMeutzner...
