Aerothermal and clearance challenges are increasingly critical with the drive towards small cores. In this simulation, a CHT simulation was used to provide the solid temperature field for a full-annulus stability prediction of the compressor at a critical operating point during a Bodie transient.

The geometry used is a design included with the MULTALL suite: Denton, J. D. (2017), MULTALL - An Open Source, CFD Based, Turbomachinery Design System, J. Turbomach. 139 (12)
