The MDAO framework has become an essential part of almost all fields, apart from mechanical, transportation, and aerospace industries, for efficient energy conversion or otherwise. It enables rapid iterative interaction among several engineering disciplines at various fidelities using automation tools design improvement. An advanced low to high fidelity is developed ducted unducted turbomachine...

This research discusses developing an Euler turbine-based hybrid mesh turbomachinery. Within the framework of mechanical engineering science, turbomachinery classification and a novel method for design were considered. In such turbomachine, large blades are replaced by set smaller blades, which interconnected to form flow channels in structure. Previous studies (and reasoning within inductive d...

The lack of established optimal design guidelines for turbomachinery operating in the nonideal flow regime (e.g., organic Rankine cycle turbines, compressors, compressors refrigeration systems) demands effective and efficient automated methods. Past research work focused on gradient-free methods applied to computational fluid-dynamic simulations. application adjoint method is a cost-effective a...

Abstract Numerical simulations of particle-laden flows have received growing attention in the last decade, due to broad spectrum industrial applications which discrete phases prediction is interest. Among these, ingestion particles by turbomachinery an area that seeing vivid research and studies. The most common technique tackle this kind problem Eulerian–Lagrangian method, individual are track...

The potential for improved performance of wave rotor cycles through the use of passage height variation is examined. A Quasi-one-dimensional CFD code with experimentally validated loss models is used to determine the flowfield in the wave rotor passages. Results indicate that a carefully chosen passage height profile can produce substantial performance gains. Numerical performance data are pres...
