TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)

The NASA code OVERFLOW is used extensively by academia, government institutions, and industry for a wide range of applications. Successful completion of Phase 1 and 2 efforts will enhance the solver and provide more accurate computations. These computations can be used to better understand the underlying physics of stalled and unsteady flow. Specifically, the advanced model can be used to test a variety of configurations that can reduce the drag of commercial transport aircraft. It can also increase the understanding of dynamic stall in rotor blades and other highly unsteady complex flows.

This model has shown improved Turbulence modeling for stall prediction for UH-60 Blackhawk in the NASA solver OVERFLOW. More validation will allow inclusion into official OVERFLOW code released to industry and government partners. Industry can use this advancement to current and future advanced aerospace designs. Improved stall prediction and more accurate drag calculations increase the use of CFD, improve designs, and reduce the need for expensive experiments

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The improved turbulence modeling can be used for future aerospace designs for a variety of NASA commercial applications. It is applicable for both aviation and space applications.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The improved turbulence modeling is equally applicable for non NASA Commercial Applications.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
