Low Temperature Combustion – A Thermodynamic Pathway to High Efficiency Engines
This article makes the argument that compression ignition combustion processes that are “flameless” with volumetric energy release, described as Low Temperature Combustion (LTC), are a thermodynamic pathway to maximizing the efficiency of reciprocating piston, internal combustion engines. The argument is built from the foundation of determining the maximum theoretical efficiency for an IC Engin...
متن کاملThermodynamic Methods of High-temperature Measurement
Thermodynamic temperature measurement techniques fall into three separate classes: pneumatic devices, heattransfer gages, and calorimetric methods. All three are characterized by the ability to measure temperatures (or related fluid properties such as enthalpy) at levels beyond the capability of thermoelectric materials or pyrometer calibration devices. The pneumatic probe consists of a tube ha...
متن کاملInvestigation of the Flow and Cavitation in a Butterfly Valve
Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...
متن کاملAn Average Flow Model of the Reynolds Roughness Including a Mass-Flow Preserving Cavitation Model
An average Reynolds equation for predicting the effects of deterministic periodic roughness, taking JFO mass flow preserving cavitation model into account, is introduced based upon double scale analysis approach. This average Reynolds equation can be used both for a microscopic interasperity cavitation and a macroscopic one. The validity of such a model is verified by numerical experiments both...
