Abstract:
In the domain of compressors, a variety of them are employed according to their respective needs. For instance, axial compressors are being used heavily in high flow rate applications on the other hand offering large compressor ratios we have centrifugal compressors and so on. But the idea of designing one, catering one to your needs has always been an intimidating element of turbomachinery.
The solution of this resides within using commercial software but they cater primarily to OEM requirements. Our project attempts to create a software that would cater its input requirements according to the user thus minimizing prior extensive knowledge and, in the end, provide them with geometric and performance parameters while also displaying their respective charts.
Within this project, a software capable of understanding user requirements and giving them a set of dimensions and plotting performance charts was created. The program calculates these parameters while paying heed to the dimensional constraints of the user. The program uses isentropic efficiency, work isentropic and specific diameters to begin its initial results, then by appropriate assumptions it proceeds by calculating geometric parameters at each stage. Finally, alongside giving output parameters it plots performance charts that give an indication of surge and choke limits. Finally, the program was tested by verifying against Design point data using CFD (ANSYS CFX) and a commercial software (CTrend).
