【 摘 要 】

In recent years, the use of micro-jet engine increased is likely to continue to grow because of the ever-increasing applications such as: an unmanned aerial vehicle and small missiles. Many industrial applications used different technics to provide an effective means for the turbine blades heat transfer. The paper presents an approach to investigate turbine blades cooling ways for microjet engines based on internal cooling passages for the blade manufacturing from Nickel base Superalloy. The numerical model considered include fluid flow and heat transfer in the turbine blade. The results agreed with experimental data. The novelty of this work to gain more in physical insight process and sensitivity analysis of cooling small size turbine blades with size 160 mm2 cross section.
