Coupled VSTOL Aircraft and Ship Airwake Turbulent Flow Simulation Model
Abstract
The objective of this SBIR program is to develop an efficient computational tool for the prediction of the complex coupled flow field of a VSTOL aircraft and a ship airwake. The proposed approach couples a hybrid chimera/overset mesh methodology with hybrid advanced flow solver methodology for the VSTOL aircraft and ship air wake flow predictions. This approach utilizes a pressure-based flow solver for the low-speed flow of the ship, and a density-based flow solver for the high-speed flow of the VSTOL aircraft. The focus of this Phase I study was to develop and validate the computational capability to separately predict an aircraft VSTOL flow field and flow over a ship structure. A density-based flow solver, CFD-FASTRAN, using blocked, structured meshes, was validated for VSTOL applications. A pressure-based flow solver, CFD-ACEU, using unstructured Cartesian meshes, was validated for ship airwake applications. To demonstrate the viability of the proposed approach for prediction of the complex, coupled VSTOL aircraft/ship airwake, a simulation of a JSF in hover and a solution for a coupled structured aircraft/Cartesian ship were also obtained.
