Modelling Fluid Dynamics, Heat Transfer and Valve Dynamics in a Reciprocating Compressor

In the present study oneand two-dimensional numerical models are proposed for calculating gas flow and valve dynamics in a reciprocating compressor. It turns out that they are capable of capturing the most important physical effects during a compression cycle, namely the interaction between pressure waves inside the cylinder and valve dynamics. In order to model the heat transfer from the gas t...

Time Resolved Mass Flow Measurement for a Reciprocating Compressor

The instantaneous mass flow was measured during the intake and discharge processes of a reciprocating gas compressor (1)*. The purpose of these measurements was to identify the mechanism which caused a loss of adiabatic and volumetric efficiency that could not be accounted for by valve flow losses. The measurements were made wi ·th square-edged orifices and fast response differential pressure t...

Mathematical modelling of Sisko fluid flow through a stenosed ‎artery

In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...

Performance Prediction of Reciprocating Compressor

The technique of the modeling and analysis procedures of reciprocating compressor is described which predict the basic performance of the compressor, compute the pressure pulsations in cylinder and suction line and simulate valve motions. The polytropic process assumption was used for modeling cylinder thermodynamic process and four-pole transfer matrix for gas pulsations and spring-mass model ...

Thermal Analysis of a Hermetic Reciprocating Compressor

The development of more efficient hermetic compressors for refrigeration involves a sound analysis of the heat exchanges inside the machine to evaluate the interaction among compressor structure, flow characteristics, refrigerant properties and operative conditions. This work presents a computational procedure for the steady-state thermal analysis of a hermetic reciprocating compressor. The mac...
