Nielsen Engineering & Research provides all levels of aerodynamic and hydrodynamic design and analysis ranging from basic engineering methods to advanced CFD calculations.
These tools, coupled with NEAR's capabilities for analyzing complex fluid phenomena, are applied to customer's problems to achieve accurate and efficient solutions.
Practical project experience in both analytical and experimental aerodynamic techniques is the basis for NEAR's excellent reputation for delivering results for commercial programs.
NEAR has a highly competent and innovative staff of scientists and engineers. Areas of competence range from applied aerodynamics analyses to basic research into the fundamental aspects of fluid phenomena. The small size of the company is an asset which allows for quick and cost effective solutions to real problems.
The experienced staff at NEAR employs the most up-to-date analytical tools to solve clients' needs accurately and efficiently. Analytical techniques readily available range from database methods to the most advanced Navier-Stokes CFD models.
Besides our proprietary codes, NEAR has experience using government developed aerodynamic codes such as the US Naval Surface Warfare Center (NSWC) Aero-Prediction codes AP98 thru AP05, the US Air Force's Missile DATCOM, (aka Digital DATCOM or USAF DATCOM) along with NASA's Aerodynamic Preliminary Analysis System APAS, MADM, SHABP, HABP (Hypersonic Arbitrary Body Program), and PMARC, a potential flow solver. NEAR also maintains a variety of CFD codes such as OVERFLOW and CFL3D, two Navier-Stokes solvers developed by NASA Ames and Langley Research Centers, respectively. OVERFLOW is also capable of inviscid solutions in Euler mode. A Navier-Stokes code developed by NASA Langley named LAURA can be used for aerodynamic heating, chemical equilibrium and nonequilibrium hypersonic flows.
