Simulation of turbine with bypasses

In this paper, the three-stage high/low pressure turbines, strut passage after turbines, bypass and mixing section are simulated numerically. Flow field structures and corresponding analyses are presented. The results indicate that simulation of multi-assembly is necessary, which is an efficient way to consider components matching. The results also show that the matching of turbine and strut is not perfect, but the flow direction is still close to axial through it. The mixing process is not intensive in the mixing section, and the loss due to mixing is not serious.
