TPFL Unsteady Turbine Cascade Research Facility

• The facility is designed to study the effect of
• Periodic unsteady inlet flow condition,
• Turbulence intensity and,
• Reynolds number
• On
• Boundary layer transition, separation,
  re-attachment and
• Heat transfer
• Furthermore, it is used for measuring
• Blade total pressure loss coefficient,
• Blade aerodynamic behavior at design and off
  design incidence, stagger angle and
• Surface roughness effects
• Please see next slide
