A 3D Navier-Stokes CFD Code for Analysis of Turbomachinery

The ADPAC software is a computational fluid dynamics (CFD) code for analysis of flows in turbomachines. The outstanding feature of ADPAC is the ability to solve the Navier-Stokes equations for complex three-dimensional (3D) flow fields that include multiple flow paths, and the modeling of which typically involves multiple computational grid blocks. In addition, ADPAC can handle coupled calculations in which some portions of models are rotating and some are not, as in the case of the rotating blades and stationary vanes of a turbomachine. ADPAC was developed especially for use in analyzing the performances of short-duct, ultrahigh-bypass-ratio turbofan engines, both as uninstalled and as installed; however, ADPAC is applicable to a very broad range of other turbomachines and of other flow systems.
