Analytical Modeling A simpler model for heat transfer was also tried by assuming a constant value for the heat transfer coefficient. The constant was obtained by finding the time average of the heat transfer coefficients obtained from Adair et al's model. Surprisingly, the simplistic model itself appears to fair better than Adair et al's model as could be seen by the satisfactory agreement in the negative lobe when the heat is being transferred from the wall to the gas. However, it should be noted that the value of the constant itself was obtained from Adair et al's model. The basic objective.
Regenerative heating is one of the stages in suction gas heating.
The gas gets heated in the cylinder passages, valve crab, valve passages and inside the cylinder itself by regenerative heating as well as indirect heating occurring as a result of throttling in the valve. It should be noted that regenerative heating could not be isolated from indirect heating inside the cylinder as well as the heating during passage through the valve. Break-up of Capacity Loss during Various Stages of Suction Gas Heating Obtained from Experimental Data. The capacity loss due to regenerative heating was also calculated from the cylinder wall heat transfer rate distributions predicted using Adair et al's model. The prediction was done using the second method which uses the experimentally measured gas and wall temperature data.
