Abstract EN
Liquefied gas reaction turbines are subject to the hydraulic affinity laws.
Particularly for liquefied hydrocarbon gas-driven turbines, deviations from the affinity laws are encountered.
In the case of reaction turbines, where the geometry is fixed, the affinity law relationships between flow, head, and rotational speed are relevant.
Field experience confirms that the affinity law relationships are adequate, but that the predictions made also tend to deviate from real turbine performance.
Part of the deviations seen may be attributed to the nonideal fluid; however, further examination is warranted.
This paper presents an investigation into the affinity law relationships between head, flow, and rotational speed in conjunction with actual turbine performance.
The three basic affinity law relationships are combined to form the most general performance equation.
This equation subsequently incorporates both the affinity law relationships and the conservation of energy principal.
Application of real turbine test data shows that this general performance equation presents a more accurate representation of turbine performance than the affinity law relationships alone.
