Innovative fluid simulation design tools for engineers
Fluid simulation can impinge on many areas of medical device design: from breathing apparatus to simulating blood flow, fluid simulation can provide insight from the earliest stages of concept design. Mentor Graphics offers a range of solutions to aid engineers responsible for fluid system design, medical equipment or clean rooms/fume cupboards.
Size components, virtually prototype different design scenarios.
Airflow is a complex phenomenon, subtle geometry changes or changes in temperature can result in very different flow patterns. This has particular importance where the designer needs to consider the dispersal of pollutants in laboratories, cleanrooms or hospitals. A thorough understanding of the response over a range of likely operating scenarios is essential:
For cleanrooms it is important to trace numerous contaminants through it- whether they are clothing particles or other larger sources of contaminants.
In healthcare facilities, airborne viruses and bacteria can be a threat to both patients and staff. These can have a devastating impact depending on where this exposure occurs, whether it’s in a patient room, isolation room or operating room. It is important to be able to control or eliminate these contaminants through the effective design of ventilation systems.
In laboratories, it is important that the overall ventilation system for the space does not compromise the effectiveness of the fume hoods. In particular, potentially hazardous chemical vapors could escape from the fume hood and create danger for the scientists within the room.
FloEFD’s CAD embedded simulation package combines a unique approach to meshing with demonstrably high levels of accuracy. It can thus be readily applied to complex geometries and scenarios. FloEFD can deliver information on both comfort parameters and calculate local mean age and local air change index parameters. It also allows tracer studies to be carried out to track the dispersal rate of gases and particulates.
FloVENT offers a powerful solver to quickly assess the ventilation of internal environments. Designed specifically for this task, its interface is designed to aid engineers in obtaining useful results quickly and easily. FloVENT features a comprehensive model creation environment for HVAC airflow modeling design. A wide range of models can be assembled quickly from a complete set of SmartParts (intelligent model creation macros). SmartParts capture modeling expertise, streamlines model creation, minimizes solve times and so maximizes solution accuracy.
Analysing performance in a virtual environment enables designers to try more innovative concepts.
Design of Heat Exchangers
The design, selection and placement of heat exchangers is of increasing importance given the trend toward increased interaction between systems; constraints on size and weight and the increased emphasis on efficiency. Computational fluid dynamics offers those concerned with these issues the opportunity to consider not only novel unit designs, but also the performance of the system as a whole under different scenarios.
FloEFD’s CAD-embedded CFD solution enables designers to assess the performance of new designs without the need to learn a new interface. Furthermore, its unique meshing system allows even the most complex geometries to be tackled with the minimum user effort.
Flowmaster’s library of heat exchanger components provides a powerful resource for those considering the system level response of a heat exchanger network. The library ranges from the very basic through to sophisticated models that allow engineers to study different geometrical arrangements within the heat exchanger. And users may enhance the catalogue with their own performance data if desired.
Create safe and well ventilated work environments with modern simulation tools.
It is increasingly the case that modern devices, of whatever type, are both smaller and more powerful than they were a decade before. Thermal management is thus an essential consideration for the designer. The number, sizing and placement of vents or fins and the internal flow paths for the cooling medium are parameters well suited to analysis via computer simulation.
Both FloEFD and FloTHERM XT leverage the power of meshing technology that enables even the most complex of geometries to be quickly and efficiently discretized. While FloEFD is an excellent CAD-embedded general purpose CFD package, well suited to the design task, FloTHERM XT focuses on electronics cooling, with a library of ‘SmartParts’ which cover the most commonly found electronic components.
