Optimization of an ORC Radial Turbine Nozzle

Organic Rankine Cycle (ORC) turbogenerators usually operate in thermodynamic regions characterized by high pressure ratios and strong real-gas effects in the flow expansion, requiring therefore a non-standard turbomachinery design. An effective approach can be based on the intensive use of Computational Fluid Dynamics (CFD) and optimization procedures to investigate a wide range of possible configurations.

Methodology

Expansions through impulse stages of ORC turbines are commonly characterized by large pressure ratios and a low speed of sound ...

Optimization of Transonic Wing with Advanced 3D Mesh Morphing

Aerodynamic efficiency is a key aspect in commercial aircraft design as it allows reducing fuel consumption and meeting emission and performance requirements. The main goal of this work is to improve the initial shape of the wing of an innovative three lifting surfaces configuration aircraft in order to minimize drag at transonic cruise condition.

Methodology:

The classic approach to aerodynamic shape optimization requires the definition of a geometrical parameterization of the CAD model. In this case, ...
