RISEffects of Upstream Step Geometry on Axisymmetric Converging Vane Endwall Secondary Flow and Heat Transfer at Transonic Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a detailed experimental and numerical study on the effects of upstream step geometry on the endwall secondary flow and heat transfer in a transonic linear turbine vane passage with axisymmetric converging ...
Experimental Study of the Endwall Heat Transfer of a Transonic Nozzle Guide Vane With Upstream Jet Purge Cooling Part 2—Effect of Combustor-Nozzle Guide Vane Misalignment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A misalignment between the combustor exit and the nozzle guide vane (NGV) platform commonly exists due to manufacturing tolerances and thermal transience. This study investigated, experimentally and computationally, the ...
Experimental Study of the Endwall Heat Transfer of a Transonic Nozzle Guide Vane With Upstream Jet Purge Cooling Part 1—Effect of Density Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nozzle guide vane (NGV) platforms often use complex cooling schemes to mitigate the ever-increasing thermal loads on endwall. Understanding the effect of advanced cooling schemes amid the highly complex three-dimensional ...
The Effect of Step Misalignment on Purge Flow Cooling of Nozzle Guide Vane at Transonic Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study describes a detailed investigation on the effects that upstream step misalignment and upstream purge film cooling have on the endwall heat transfer for first stage nozzle guide vanes (NGVs) in a gas turbine at ...
