es-turbo

The CFD Expert System tool for the turbomachinery industry

es-turbo provides a streamlined interface, grid generator and post-processing facilities for the turbomachinery industry.

With es-turbo, it is possible to interact directly with the client's blade design system and construct a high-fidelity computational model in minutes. While initially developed to satisfy the pre- and post-processing needs of the Turbomachinery industry, es-turbo has been shown to be useful for a much broader range of applications. To date, es-turbo applications include centrifugal and axial compressors and turbines, turbochargers, torque converters, radiator fans, propellers and blood pumps, to name but a few.

es-turbo employs a multi-blocked meshing strategy to quickly generate high quality grids around aerodynamic bodies in both axial and centrifugal configurations. Using one of the predefined topologies avoids the confusion associated with many multi-block grid generators and significantly reduces the user input and hence time required to build a computational model.

The generation of the computational mesh is achieved through an iterative solution of a set of elliptic equations. These equations are constrained to match the geometric shape being meshed and are subjected to boundary conditions that guarantee smooth variations in grid clustering and orthogonality.

For more complex geometric features, such as part span shrouds, cooling holes and casing treatments, es-turbo easily interfaces with the automatic meshing capabilities of pro-STAR/amm. Geometries that would take weeks with conventional multi-block codes can now be meshed in hours.

In addition to its capabilities as a grid generator, es-turbo also allows the user to impose boundary conditions, specify thermophysical properties and define the numerical algorithm parameters required by STAR-CD. Presently, we are working with several turbomachinery companies to provide specialized post-processing capabilities to further improve engineer productivity and ease-of-use.
