What Is Computational Fluid Dynamics (CFD) Analysis?
Computational Fluid Dynamics (CFD) is a numerical engineering approach used to solve the governing equations of fluid motion and, where required, energy transport, species transport and chemical reactions.
CFD analysis helps engineers understand how liquids and gases behave within or around a component, product, machine or complete system. Depending on the application, the analysis can predict velocity fields, pressure distribution, turbulence, temperature variation, heat transfer, mixing behaviour and other relevant physical quantities.
Unlike a purely qualitative assessment, CFD provides spatially resolved numerical results that can be examined at different locations and operating conditions. These results can help identify flow restrictions, recirculation zones, thermal hotspots, uneven airflow, excessive pressure losses and other potential performance concerns.
When appropriately modeled and assessed, CFD can support engineering decisions throughout the design process—from initial concept evaluation and design refinement to troubleshooting and performance assessment.
At NCES, CFD analysis is approached as an engineering problem-solving process, combining suitable physical models, computational modeling, numerical assessment and interpretation of results to address the specific objectives of each project.
We provide a comprehensive range of Computational Fluid Dynamics (CFD) analysis services which enabled our customers to develop high quality engineered products and to strengthen their market position. Our CFD analysis capabilities includes,
Fluid Flow Analysis
Understand how fluids move through components, equipment and complex flow passages. Our fluid flow analysis evaluates velocity distribution, pressure fields, flow separation,recirculation and flow uniformity to help engineers investigate system performance and identify potential restrictions.
