TN 33: A Review of Building Air Flow Simulation

Considerable developments in the area of computational fluid dynamics are currently taking place, especially in relation to refinements in calculation techniques. The objective of this report is to outline developments in building airflow analysis and to focus on some of the difficulties associated with this complex field of study. These include a brief synthesis of the relevant flow equations, the results of the AIVC's survey into the application of airflow codes for building airflow simulation, and summaries of selected public domain and commercial general purpose algorithms.
