PHOENICS Building-related Case Studies & Demonstration Examples

FLAIR - HVAC & Internal & External Flows

FLAIR is a special-purpose version of PHOENICS, designed to provide an air-flow and thermal-simulation facility for the HVAC community, and for those concerned with fire, smoke and pollutant hazards, for both internal and external flow scenarios.

FLAIR predicts air-flow patterns, temperature distributions and smoke movement in buildings and other enclosed spaces. FLAIR can be used during the design process to detect and avoid uncomfortable air speeds or temperatures.

In addition it can predict effects of smoke movement, or any other gaseous pollutant, helping to achieve safe design of buildings, underground systems, aircraft or train cabins etc. FLAIR can also be used by various regulatory bodies and safety consultants.

Professor Brian Spalding received a degree of Doctor of Science honoris causa from Imperial College at the beginning of May. Brian has been associated with IC from 1954 when he was invited to join from Cambridge. He started as Reader in Applied Heat, in 1958 was appointed to the Chair of Heat Transfer and, subsequently was also Head of the Computational Fluid Dynamics Unit. He remained Professor of Heat Transfer and Head of CFD until his retirement in 1988. The doctorate was awarded for services to science and to CFD of which he is a founding father.
