Optimization of a novel impulse gas turbine nozzle and blades design utilizing Taguchi method for micro-scale power generation

This study is conducted to optimize the nozzle and blade of a compact non-combustion impulse gas turbine driven by the pressurized gas line with Computational Fluid Dynamics (CFD) approach and Taguchi method. For nozzle, throat diameter, nozzle inlet and outlet diameter and convergent-divergent leng...
