Computational Aeroacoustics (CAA) Consulting Services

Computational Aeroacoustics (CAA) | A critically overlooked sub-branch of Computational Fluid Dynamics (CFD)

Noise is an integral part of almost every device around us, and has become a core focus in Computational Aeroacoustics (CAA).  Vehicles, electronic tools and even the wind can cause such high Sound Pressure Level (SPL) that can disturb both the environment and the lives of citizens inhabiting a particular area.

Thankfully, the noise generated from flowing fluids can seamlessly be calculated with our custom software, in addition to our 25+ years of experience in aerospace and aeroacoustical analysis’ and on-staff engineering expertise.

Quickly and Reliably Respond to Air and Fluid Flow Challenges

Computational Aeroacoustics (CAA) Consulting

Aeroacoustics consulting engineers from SimuTech Group are respected experts in the combined study of aerodynamics and acoustics, or “aeroacoustics,” across all of North America.

Our engineers are well-versed in using cutting-edge Computational Fluid Dynamic (CFD) modeling technologies to solve challenging engineering and architectural design issues. As a result, they offer client management-design teams the solutions they need to either implement the most recent, high-performance system or building designs or to identify and fix an existing issue.

In addition, aeroacoustics CFD simulations from SimuTech Group are used to simulate aerodynamic and hydraulic designs (generically referred as “fluid flows”). The CFD science enables the following determinations:

3D Visualizations of Site or System Dynamics via Pre-Construction CFD

Investigating System Reactions to Prevailing Climatic Wind

When fluid flows inside or around a building, advanced computer modeling can predict what will happen statistically, graphically, and animatedly. In order to model a 3D structure, our engineers replicate real-scale geometry during pre-construction CFD (computational fluid dynamics) study.

Computer simulations of the suggested layouts, choices, and/or various physical, fluid, and/or climatic conditions are carried out, providing information and visuals of what will occur in reality when certain conditions, physical shapes, events, and weather situations occur.

Finally, these findings are then used to inform the design during the engineering phase or as suggestions for correction – as a source of information, ideas, or tactics.

Using CFD to Predict Aerodynamic and Hydraulic Performance

Using the principles of established fluid flow, CFD forecasts 3D aerodynamic and hydraulic performance inside and outside of a structure, enabling the capacity to troubleshoot and confirm effective designs. Essentially, it enables decision-makers, engineers, and regulatory agencies to see what happens within and around a hypothetical or actual structure with a level of visual animation and detail that is impossible to see firsthand using wind tunnel modeling, smoke tracing, and/or area sampling.

When SimuTech Aeroacoustics CFD skills are used during the project design phase, theoretical notions are confirmed and cost effectiveness is achieved through system efficiencies. Expensive and useless “cut and try” attempts are prevented thanks to this robust diagnostic tool employed with computational aeroacoustics (CAA) consulting.

Empirically Substantiated Analysis with Scale Model Testing

CFD offers insight into how the design will perform based on a solid scientific foundation by modeling fluid flow in 3D on a prospective or existing design. If necessary for the project, recommendations can be experimentally supported through large-scale wind tunnel performance.  Or, via scale model testing on our own Aeroacoustics aerodynamic flow bench.

An engineering management team will receive sound solutions from our CFD design analysis and/or remedial diagnostics.  This is our promise so that your team can make decisions quickly, choose the best design, and save money on prototyping.

Allow a skilled SimuTech Group Aeroacoustics engineer to help you create a successful protocol and a timetable for deployment. Let us ease your job with our nearly 25 years of experience and dozens of successful projects under our belt.
