Influence of Fluid Dynamics on Heat Transfer in a Preswirl Rotating-Disk System

Modem gas turbines are cooled using air diverted from the compressor In a "direct transfer" preswirl system, this cooling air flows axially across the wheel space from stationary preswirl nozzles to

Performance of Pre-Swirl Rotating-Disc Systems

This paper summarizes and extends recent theoretical, computational, and experimental research into the fluid mechanics, thermodynamics, and heat transfer characteristics of the so-called cover-plate

Computational fluid dynamics analysis for effect of length to diameter ratio of nozzles on performance of pre-swirl systems

In a direct-transfer pre-swirl system, cooling air expands through stationary pre-swirl nozzles and flows through the cavity to the receiver holes located in the rotating turbine disc for blade

Heat transfer measurements using liquid crystals in a preswirl rotating-disk system

Preswirl nozzles are often used in gas turbines to deliver the cooling air to the turbine blades through receiver holes in a rotating disk. The distribution of the local Nusselt number, Nu, on the

Pre-swirl rotor-stator systems: Flow and heat transfer

This thesis compares previously published heat transfer measurements from a pre-swirl rotor-stator experiment with 3D steady state results from a commercial CFD code. The experimental distribution of

Fluid Dynamics of a Pre-Swirl Rotor-Stator System

In a direct-transfer pre-swirl supply system, cooling air flows axially across the wheel-space from stationary pre-swirl nozzles to receiver holes located at a similar radius in the rotating turbine
