Airflow Design with Simulation

3D Airflow Modeling Software Overview Since 1988, our Mechanical Analysis Division has played a pioneering role in the simulation of airflow in and around buildings by delivering high-quality analysis software for designers. The result is powerful Computational Fluid Dynamics (CFD) software called FloVENT, which predicts 3D airflow, heat transfer and contamination dispersion in both internal and external environments. Why Perform Airflow Modeling No matter how complex your airflow application is, modeling enables you to understand it more comprehensively through the medium of virtual reality...

“Using FloVENT, we can review a number of design scenarios early in the development cycle, which helps to reduce bottlenecks and improve engineering performance.” Ian Matthews, Engineer, Buro Happold w w w. m e nto r. co m 3

Solver and Design Optimization Parametric Analysis and Optimization SmartPart-based modeling and structured Cartesian grid enable Design of Experiments (DoE) technology to be applied to a FloVENT model. Design of Experiments is a structured method for determining the relationship between design parameters (e.g., diffuser flow rate, location of vents, etc) and results (comfort indices, contaminant removal efficiency, etc). FloVENT’s Design of Experiments implementation efficiently explores the design space by building and solving variants of the initial model. This provides critical information...
