Tenders or technical terms contain a large quantity of both technical, legal, managerial information mixed in a nested and complex net of relationships. Extracting technical and design information from a document whose aim is both legal and technical, and that is written using several specific jargons, is not a trivial task: the purpose of the rese...

The reduction of pressure losses is one of the most important challenges for the efficiency increase of a reciprocating compressor. Since the absorbed power is strongly affected by the losses through pocket valves and cylinder ducts, an accurate prediction of these losses is essential. The use of computational fluid dynamics (CFD) simulation has sh...

The increasing demand for high efficiency in the field of energy production has also had an impact on reciprocating compressors. In this case, the need to reduce losses is one of the most important challenges. In the past, most studies were focused only on the analysis of valve pressure losses. More recently, interest has been extended to the predi...

Reciprocating compressor efficiency is driven by the pressure losses generated at suction and discharge. While the valves are the major contributors to these losses, a key role is played by other components along the cylinder suction and discharge paths. CFD simulations of complete systems are a viable solution for prediction of total pressure loss...

Pressure losses in the suction and discharge components of a reciprocating compressor are the main irreversibilities that affect the global system efficiency; their prediction is a critical issue for the evaluation of the absorbed power. Flow coefficients for automatic valves are often derived from experimental data obtained on a dedicated test ben...
