Abstract
The design of centrifugal compressors is a vast subject in several industrial applications that can be approached in different ways and from the perspective of different design methodologies. Naturally, because of this multitude of different approaches, it makes the design teaching task of these machines labourious, and students may have many doubts in choosing the best option. As an attempt to assist the students in the design process, this paper proposes a methodology that was implemented in a tool capable of assisting in the design teaching of these mechanisms. A one-dimensional computational code using Python language was written, with the addition of appropriate loss modeling to enhance the machine prediction at design-point. The developed computational code is based on examples from open literature, in order to lead to a step-by-step design procedure. Also, the interface has several graphic interfaces that help the designer understanding in each of the design stages, availability for the user to work with different slip factor models and other considerations on the losses associated with these machines. Moreover, it is flexible to implement new subroutines to improve its capabilities. To enable the student himself to self-assess whether the data being entered is compatible with good design practices, several alerts have been programmed to guide the user about possible problems related to its sizing, as an example. It is possible to vary one of the design parameters, so that it is possible to analyze its influence on the performance characteristics of the machine. Using the developed tool, the students will be able to better understand the design process of a centrifugal compressor, developing it for a required condition.
