“…Firstly, the mass flow rate and energy flow through the ports contiguous to chambers are used as inputs to the thermodynamic integral solution. Differential Equations (9), (10) or (25) and (20) correspond in sequence to the first law of thermodynamics, the continuity equation and valve dynamic are calculated simultaneously by using the standard 4th order Runge-Kutta method. Specific internal energy e and gas mass m inside control volumes can be obtained and one can compute the instantaneous density by:…”

“…Hwang et al [9] investigated the behavior characteristics of a circular plate discharge valve in a liner compressor. Bin et al [10] investigated the effects of an RNG k-ε turbulence model and a DES turbulence model on pressure pulsation. Results demonstrated that the former model reproduced pressure pulsation below 500 Hz fairly well, while the latter model enhanced the limitation to 1500 Hz.…”

This work investigates the effects of pressure pulsations on reciprocating natural gas compressor performance thermodynamically. A nonlinear hybrid numerical model is thus developed to consider the interaction between the compressor and the pipeline system. The suction chamber, compressor cylinder and discharge chamber are modelled integrally based on the first law of thermodynamics and mass balance, and the pipeline flow is described by using the gas dynamic model. Methane is considered as the working fluid and its properties are computed based on ideal and real gas assumptions. For the real gas model, the methane properties are obtained by means of calling the NIST REFPROP database. The validity of numerical results is confirmed by previous experimental values. Results from the examinations of pressure pulsation influence demonstrate that discharge resonance requires more specific work than suction resonance in the same harmonic; in the suction system, the first harmonic response reduces the mass flow rate but significantly increases specific work, and the second harmonic response has a strong supercharging effect but the specific work is increased slightly; in the discharge system, the mass flow rate is changed little by pressure pulsations, but the indicated power and specific work are increased significantly; for the real gas model, the in-cylinder temperature during the compression and discharge phases, mass flow rate and indicated power are higher than those for the ideal gas model, whereas the specific work is less for the real gas model than for the ideal gas model.

“…With the advances in the simulation capabilities of the computers, studies of 3D models employing Fluid-Structure Interface (FSI) have been developed. In a study by Zhao et al [14], the mesh mapping method, the dynamic mesh technique and 3D CFD model were employed to simulate the ringvalve motion and to study the fluid flow through the valve. RNG k-ε turbulence model and the standard wall conditions were employed to study the fluid flow.…”
