Abstract

This research presents the results of numerical and experimental study of thermal distribution and airflow over a reciprocating compressor. The air volume enveloping the motor core, motor cover and cylinder blocks is studied. To form the base case, a numerical investigation with the temperature settings obtained from a laboratory test is conducted. The model is then tested with different fan capacities, position and size of inlets and outlets and heat inputs. The results indicate that the change in the settings has a considerable effect in heat transfer and pressure drop characteristics. This change is mainly due to the variation of air that is drawn in, which flows over the hot surfaces causing higher heat transfer. The data and conclusions of this study can be applied to the design of compressors to find the optimum settings. It can also be used in the design of electronic assembly boxes. This study also demonstrates that numerical models backed with experimental analysis could reduce both the time and money required to create and evaluate engineering concepts, especially those that deal with fluid flow and heat transfer.
