To provide an overview of the current state of the art of heat transfer augmentation schemes
employed for internal cooling of turbine blades and components, results from an extensive …

Transition between nucleate and film boiling potentially causes dramatic temperature
changes during fluxcontrolled operations, which may lead to catastrophic equipment …

A novel turbine film-cooling hole shape has been conceived and designed at NASA Glenn
Research Center. This “antivortex” design is unique in that it requires only easily machinable …

The primary focus of this paper is convective heat transfer in axial flow turbines. Research
activity involving heat transfer generally separates into two related areas: predictions and …

A combined experimental and computational study has been performed to investigate the
detailed distribution of convective heat transfer coefficients on the first-stage blade tip …

Computations were performed to study the three-dimensional flow and heat transfer in a U-
shaped duct of square cross section under rotating and non-rotating conditions. The …

We report on the progress in the development and application of a coupled boundary
element/finite volume method temperature‐forward/flux‐back algorithm developed to solve …

Calculations were performed to assess the effect of the tip leakage flow on the rate of heat
transfer to blade, blade tip, and casing. The effect on exit angle and efficiency was also …

A concept for mitigating the adverse effects of jet vorticity and lift-off at high blowing ratios for
turbine film cooling flows has been developed and studied at NASA Glenn Research Center …
