Axial Compressor Deterioration Caused by Saltwater Ingestion
TLDR
In this article, the axial compressor of a General Electric J85-13 jet engine was degraded by spraying atomized droplets of saltwater into the engine intake, and the results of laboratory analysis of the salt deposits are presented, providing insight into the increased surface roughness and the deposit thickness and distribution.Abstract:
Gas turbine performance deterioration can be a major economic factor. An example is within offshore installations where a degradation of gas turbine performance can mean a reduction of oil and gas production. This paper describes the test results from a series of accelerated deterioration tests on a General Electric J85-13 jet engine. The axial compressor was deteriorated by spraying atomized droplets of saltwater into the engine intake. The paper presents the overall engine performance deterioration as well as deteriorated stage characteristics. The results of laboratory analysis of the salt deposits are presented, providing insight into the increased surface roughness and the deposit thickness and distribution. The test data show good agreement with published stage characteristics and give valuable information regarding stage-by-stage performance deterioration.read more

Fouling Mechanisms in Axial Compressors
Rainer Kurz,Klaus Brun +1 more
TL;DR: Fouling is caused by the adherence of particles to airfoils and annulus surfaces, and the result is a build-up of material that causes increased surface roughness and to some degree changes the shape of the airfoil as mentioned in this paper.
