Transient Three-Dimensional Side Load Analysis of Out-of-Round Film Cooled Nozzles [PDF]
, 2010 The objective of this study is to investigate the effect of nozzle out-of-roundness on the transient startup side loads. The out-of-roundness could be the result of asymmetric loads induced by hardware attached to the nozzle, asymmetric internal stresses
