When designing a new compressor or pump, most of the focus is put on the impeller and diffuser because they are the elements that are responsible for the work input and its conversion from kinetic energy into static pressure. However, they are not the only elements in a typical turbomachine stage. The volute can also play a significant, and sometimes dominant, role in stage performance. This blog will explore important factors in volute design.

When designing turbomachines, the quality of the final product can often be improved by implementing a holistic approach to the engineering process. As with many complex mechanical systems there are a significant number of competing requirements that impact the overall success of the system. By fully understanding the nature of these compromises, and how the various subsystems interact, the design will be improved. This interplay is particularly noticeable in the design of integrally geared (IG) turbomachinery.

Once when asked about his priorities, British Prime Minister Tony Blair replied, “Education, education, education.” We can be sure he was not thinking specifically about courses in mechanical engineering, but his proclamation does highlight the fact that nobody in or out of public life can neglect the need for more or better knowledge.

The vast majority of turbomachinery textbooks emphasize analysis when the heart of engineering is based in design. Concepts NREC is uniquely qualified to share the nature and process of engineering design. When Concepts NREC decided to write and publish a range of turbomachinery textbooks, the objective was to emphasize engineering design rather than analysis.
