Analysis of the Effect of the Compressor Kinematics on the Valve Losses
نویسنده
چکیده
Flow losses through the valve ports contribute a significant portion to the total energy loss of a high speed compressor. As a result, in the energyconscious world of today, compressor designers are always busy finding methods and techniques to minimize these losses. It can be argued that the various fundamentally different compressor concepts would have different valve flow losses simply as a result of the difference in the kinematics of their operation, even if other factors including the valve characteristics were the same. An attempt has been made in this paper to highlight this difference by way of simple mathematical relationship between the kinematic characteristics of a compressor and the corresponding flow losses. Four different kinematic arrangements of the reciprocating as well as the rotary concepts were picked up for the analysis. The results indicate a rather interesting perspective for the compressor designer to keep in mind.
