Dynamic Behavior Characteristics of Piston in Reciprocating Compressor

Dynamic Characteristics of a Free Piston Compressor

The design and dynamic characterization of a free piston compressor is presented in this paper. The free piston compressor is a proposed device that utilizes combustion to compress air into a high-pressure supply tank. The device is configured such that the transduction from thermal energy to stored energy, in the form of compressed gas, is efficient relative to other small-scale portable power...

A 3-D Transient CFD Model of a Reciprocating Piston Compressor with Dynamic Port Flip Valves

In this paper a full transient 3-D CFD model of a complete single piston compressor system along with dynamic inlet and outlet port flip valves is presented. The model includes the motion of the cam driven piston, and also predicts the motion of the dynamic flip valves. All activities related to model creation, simulation and postprocessing were performed within the simulation software Simerics...

Dynamic Simulation Model of a Reciprocating Compressor in a Refrigerator

In this paper, a set of mathematical model to be used for predicting the dynamics of a reciprocating compressor in a refrigerator has been developed. Based on the conservation of energy and mass, the model was established by dividing a global compressor into ten controlling volumes. The model was validated by the experimental results from literatures. It could be calculated for the transient ch...
