Résumé

This paper presents a numerical analysis of the unsteady in-cylinder heat transfer for a simplified model of a small reciprocating compressor under actual operating conditions, with an assessment of the influence of suction and discharge processes. A two-dimensional finite volume model is used to numerically solve the associated turbulent flow field, whereas the dynamics of valves is described by a one-degree of freedom model. Numerical results are provided for the instantaneous heat transfer at different wall surfaces inside the cylinder. Additionally, predictions for heat transfer are compared with estimates of correlations available in the literature. It is found that heat transfer is strongly affected by suction and discharge processes and this aspect is not well represented by current correlations.
