What is it about?
A modular axial compressor rig with a custom test article was subject to ice impingement. This test article was heavily instrumented with non-intrusive surface thermocouples and thin-film heat transfer gages. We present a tool to correlate and augment these sensors to resolve across the surface and with time the temperature and heat transfer sequences. These sensors display the same behaviour and internally mounted gages and match our predictions of the icing sequence from a thermal point of view.

Why is it important?
Engine icing due to ice crystal ingestion poses a very real threat to modern turbofans - thoroughbred race horses that whilst being ultra-efficient are different to older designs. We believe events such as icing inception and shedding are closely related to heat transfer histories; understanding this sequence is key to understanding these processes.
Perspectives
This work is the second of a larger series based on the 2022 Oxford-NRC rotating rig campaign. We'll be sure to do our best to get more of the data and relations to shed observations out in future.
