Knowing that a system or component design requiring efficient aerodynamics will perform as required is critical to customers to ensure production is maximized while maintenance and operating costs are minimized. Historically systems are generically developed based on modifications of prior designs, experience, theoretical and empirical data; even though the physical installation and operational requirements are unique or fundamentally different to prior requirements. Using this form analysis can result in equipment that is over or under designed due to the assumptions used. These system designs are often perceived by customers to be a suitable solution, though at worst the equipment fails to meet the requirements or leads to higher life cycle costs through increased power consumption, low system efficiency and increased maintenance that compromises production and operating costs.
The use of computational fluid dynamics (CFD) analysis removes the assumptions and calculation errors when determining the flow path, pressure and temperature through the system to provide the optimal design.
The CFD model is created by use of a computer-generated conceptual design of the equipment that is transformed into a series of multiple three-dimensional grids. The model is then analyzed using scientifically known relationships to produce a visual analysis from which the engineer can introduce changes to finalize the design for optimal flow characteristics.
The resultant analysis and design are achieved with total confidence of the actual real-world results in far less time than the traditional methods and with less design cost. The flow simulation is run by qualified engineers who are fully conversant with the methodology and interpretation of the resultant data given to determine the optimum design configuration. Costs are further saved since the detail design and manufacture proceeds knowing that there are no further changes required and that associated flow providing equipment selected need not be oversized to account for design “safety margins”.
VG Engineering Inc. have provided numerous flow system designs developed using CFD analysis and their engineer's expertise, that when installed have met their predicted performance in full compliance to the agreed specifications of satisfied clients.
How? A form of airflow modeling, CFD analysis factors airflow direction, temperature, and pressure, with air delivery optimization to produce just-right designs. Not under-designed from the last project’s specs, or over-designed due to added-in margins, CFD is truly a triple threat:
It’s faster. Quickly identify and capitalize on performance improvement opportunities through airflow pattern visualization and modification at the conceptual stage before design progresses to subsequent phases where change is difficult and costly.
It’s better. Scientific prediction of airflow patterns, temperature, and contaminant spread over “rule-of-thumb” design guidance.
It’s cheaper. Pursuit of the most economical solution-lowest first cost, lowest operating cost, or a combination-through protective environment modeling, backed by the highest degree of confidence.
Building owners and engineers around the world consider Revit’s purpose-built 3D modeling software a best practice and best product in business information modeling (BIM). Whether you’re building a simple 2,000 SF interior space or an elaborate 600,000 SF edifice, Revit’s end-to-end system design and documentation solution delivers MEP systems that support today’s vision and tomorrow’s visionary.
Work naturally. Let Revit® MEP software transform your imaginative design thoughts into innovative function. Design, build, and maintain with a tool that’s designed and built for the way architects and engineers think.
Design freely. Revit® MEP’s parametric change technology ensures every modification you make flows through to model views, drawing sheets, schedules, sections, and plans. Change whatever you want whenever you want, with confidence that documentation and design synch up automatically as you work.
Deliver efficiently. Improved visualization from multi-dimensional calculations and design element details means issues are exposed early, while there’s still time to correct them and avoid structural impacts.
Save money. On design efficiencies, building innovations, even maintenance. For example, building owners who use Revit® MEP can perform commercial energy audits online during building walk-throughs and avoid costly site crew visits.
