A way to explore the possibility of new kinds of turbomachinery
Résumé
In this article we desire to explore the capability of conceiving new kinds of turbomachinery, and to estimate their performance and their application domain. We need to extend the classical Euler equation for turbomachinery for non relative stationary flow and non permanent fluid boundaries. To obtain reasonably tractable relations for exploratory purposes, we limit our study to incompressible non viscous flow. The simplifying chosen boundaries conditions lead to hydraulic turbomachinery type and we focus on turbines. It is possible to establish a chart of performance in the cases of limited effects of gravity on rotor flow and the domain of use is compared to classical hydraulic turbines. In other cases the model can be applied and leads to turbomachines which appear more as water wheels but it offers another way to apprehend and design them.
