With the use of advanced CFD modelling simulations, as well as evacuation modelling programs, we are able to demonstrate effective solutions that provide an appropriate level of safety within a given design, whilst providing other significant benefits to the design. CFD Online An online center for Computational Fluid Dynamics. This calculator computes the height of the first mesh cell off the wall required to achieve a desired Y+ using flat-plate boundary layer theory. This has led to the need for Designers, Fire Safety Engineers and Approving Authorities to evaluate aspects of building design by adopting CFD analysis. As the boundaries of what is possible with architectural design and building geometry, as well as operational use of buildings are pushed further, hand calculations are not always appropriate or possible. There has been a significant increase in recent times of performance-based building design.
The Y+ Calculator converts between SI and Imperial units. Nowadays, CFD is utilized in almost every development process where airflow is involved and plays an important role.
#Computational fluid dynamics calculator software
Computational Fluid Dynamics models and software started to appear on the horizon. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. The new Y+ Calculator is a handy tool for calculating the grid spacing at a wall to achieve a target y+ value for turbulent computational fluid dynamics. With the appearance of computers, the numerical calculation of the governing equations became possible. Hand calculations only provide a numerical reference with regards to the spread of smoke and heat from fires and in the case of zone modelling, a very simple computational representation of performance in a given design. This free app is a handy tool for calculating the grid spacing at a wall to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. CFD can be used to demonstrate how engineering solutions are effective in providing an equivalent level of safety to that of a code-compliant design solution.īefore the emergence of CFD simulation, practical problems with building design (outside code-compliant design) were addressed with hand calculations and basic zone modelling. This calculator will provide results for fluid dynamics, civil, structural, pipe flow, engineering parameters and more.
