FINE DESIGN

Version 1.0

THE FIRST INDUSTRIAL INTERACTIVE ENVIRONMENT FOR TURBOMACHINERY BLADE INVERSE DESIGN

Mach number distribution around initial design

Mach number distribution around new design

Reduce shock boundary layer interaction with imposed blade thickness

OBTAIN IMPROVED PERFORMANCES WITH FINE/DESIGN 1.0

Remove shock waves
Reduce shock boundary layer interactions
Remove leading edge velocity peaks
Modify blade loading distribution for the reduction of secondary flows

FIELDS OF APPLICATIONS

Axial, radial and mixed flow machines
Compressors, turbines and pumps
Subsonic to supersonic flow regimes
Centrifugal compressors with splitters

DESIGN STRATEGIES AND CONSTRAINTS

Multiple design strategies are offered to the user:

--Full inverse strategy: suction and pressure surfaces are re-designed for a prescribed pressure distribution (subsonic axial stationary components)

--Semi inverse strategy: suction surface redesigned, pressure surface deduced from thickness distribution (subsonic and transonic rotor components)

--Blade loading strategy: blade loading and thickness distribution imposed (centrifugal components, pumps)

Geometrical & aerodynamic constraints can be imposed in order to match with design constraints:

--Blade chord

--Mass flow, pressure ratio

--Outlet flow angle

--Reference point (leading edge, trailing edge, center of gravity)

Turbine blade - Navier-Stokes results: iso-Mach lines

Subsonic turbine blade - Remove leading edge velocity peaks

HARDWARE REQUIREMENTS

FINE/Design runs on UNIX platforms (HP, SGI, SUN, DEC and IBM) and on PC

Centrifugal impeller with splitters - modify blade loading distribution
