Dynamic Simulation of Positive Displacement Compressors Using Object Oriented Approach

A software tool-set, from which dynamic simulation of any type of positive displacement compressor can be constructed, is developed using an object oriented approach. This approach has three major advantages. The frrst is that a simulation code for any type of positive displacement compressor can be developed quickly with a uniform protocol. The second advantage is the ease of handling of creation, annihilation, merger and separation of compression chambers, and the changes in topology associated with them. These events are common to most types of compressors, except for the simplest reciprocal piston type. The third advantage is the ease of replacing the models of components, such as the valves or even the compression chambers themselves, as different designs or better models become available. The simulation codes are used in optimizing the design parameter of compressors being developed, as well as competitive analysis of different types of compressors that would be deployed under the same service requirements.
