different inclination from the global axes.

Pressure outlet boundary conditions require the specification of a static (gauge) pressure at

the outlet boundary.

Reference Values

The reference values to be set are Area, Density, Enthalpy, Length, Pressure, Temperature,

Velocity, Dynamic Viscosity and Ratio of Specific Heats. For the analysis, all the parameters

are set to default once we choose to compute from Inlet.

Solver

Second order discretization upwind is used to solve the problem with a pressure based

solver. Each boundary conditions are initialized with flow velocity value. Then iterations are

run.

Two pressure-based solver algorithms are available in ANSYS FLUENT, a segregated

algorithm, and a coupled algorithm. A coupled algorithm or scheme is selected for the

problem.

3.9 Determination Of Best Model
The results of simulations of various geometries where each geometry is analyzed through a

range of tip speed ratios from 1 to 2.25 due to which is considered to obtain the maximum

output are given below
