Fluid analysis integrated solution that significantly improves turbine development efficiency.

Optimization design support system specialized for turbomachinery.

The internal flow of gas turbines is characterized by unsteady physical phenomena caused by factors such as boundary layers on the airfoil surfaces, interaction between moving and stationary blades, shock waves, and tip leakage flows. However, particularly in multi-stage axial gas turbines, steady (quasi-steady) analyses are often conducted due to reasons such as the increase in mesh count. Additionally, complex features like fillets, three-dimensional leakage paths, and cooling holes can make it difficult to generate accurate grids due to their complexity, posing challenges for turbine designers. This article introduces three solutions provided by the Japan Cadence NUMECA sales team to address the issues faced by gas turbine designers mentioned above. The first is AutoGrid5, a grid generation software that automatically generates complete hexahedral grids for complex turbomachinery, taking into account features such as fillets and cooling holes. The second is FINE/Turbo, a turbomachinery fluid analysis solver that conducts fluid analysis with high speed and accuracy, particularly capable of rapidly analyzing the interaction between moving and stationary blades in turbomachinery. The third is FINE/Design3D, an optimization design support system specialized for turbomachinery, which enables optimization design that has been increasingly demanded in recent years.
