... the improved bend designs in internal cooling channels. internal cooling two-pass channel bend geometry The efficiency of a gas turbine engine is strongly dependent on the turbine inlet temperature and as a result, modern gas turbine engines are operated at temperatures that approach 1800–2000...

... that the bend geometry can have a significant effect on the overall performance of a two-pass channel. The modified bend geometries are compared with the baseline using Nusselt number ratios, friction factor ratios, and thermal performance factors (TPF) as the metrics. All the modified bend geometries show...
