“…A step-bystep derivation of this process is provided by Pokhrel. 30 For the design of non-axisymmetric stators, a multipoint multi-meanline method is used. The multi-point method treats each circumferential location separately the same way the rotor was treated, except in this case, the equations for design (and not off-design) mode are solved, the idea being that the stator has to match to the incoming flow from rotor exit.…”

“…The blade geometry used in this study was obtained using a model built on the platform of Object Oriented Turbomachinery Analysis Code (OTAC) [24]. Extensions on the multi-meanline design approach have been made to account for circumferential asymmetry in the incoming flow [25]. The blade is formed by identifying three characteristic cross sections from OTAC.…”

“…But, they can be referred in Ref. [25]. Further, the analysis considers all the geometric nonlinearities associated with the blade as well as the loading due to rotation of the fan blades.…”

“…9 From the discussions above, it is clear that fans should be designed for asymmetry, and structural constraints need to be included during early phases of design. In this paper, a computational framework that captures the fan aerodynamic design approach 10 and rotor structural analysis using VAM 9 is introduced and explained. Section II provides a detailed discussion on the components of the framework to produce an optimal fan stage.…”
