Automatic Borescope Damage Assessments for Gas Turbine Blades via Deep Learning

no code implementations23 Feb 2021 Chun Yui Wong, Pranay Seshadri, Geoffrey T. Parks

Building upon state-of-the-art methods from computer vision, we show that damage statistics can be presented for each blade in a blade row separately, and demonstrate the workflow on two borescope videos.

Blade Envelopes Part II: Multiple Objectives and Inverse Design

1 code implementation31 Dec 2020 Chun Yui Wong, Pranay Seshadri, Ashley Scillitoe, Bryn Noel Ubald, Andrew B. Duncan, Geoffrey Parks

In Part I of this two-part paper, a workflow for the formulation of blade envelopes is described and demonstrated.

Blade Envelopes Part I: Concept and Methodology

1 code implementation22 Nov 2020 Chun Yui Wong, Pranay Seshadri, Ashley Scillitoe, Andrew B. Duncan, Geoffrey Parks

Blades manufactured through flank and point milling will likely exhibit geometric variability.

Uncertainty Quantification for Data-driven Turbulence Modelling with Mondrian Forests

1 code implementation4 Mar 2020 Ashley Scillitoe, Pranay Seshadri, Mark Girolami

The MF predictive uncertainty is also found to be better calibrated and less computationally costly than the uncertainty estimated from applying jackknifing to random forest predictions.

Supporting Multi-point Fan Design with Dimension Reduction

2 code implementations20 Oct 2019 Pranay Seshadri, Shaowu Yuchi, Shahrokh Shahpar, Geoffrey Parks

Our results using polynomial variable projection clearly demonstrate that one can accurately identify dimension reducing subspaces for turbomachinery functionals at a fraction of the cost associated with prior methods.
