The validation of computer predictions of physical processes is still a topic of concern, particularly in relation to dynamic thermal simulation modelling. However, far more complex computer programs are now being introduced into the building services industry. These new programs solve the conservation equations of momentum, energy and mass to simulate air movement in and around buildings. The validation task is potentially more difficult than that encountered to date. This paper discusses some of the problems associated with the application and validation of these codes and suggests how a user can ensure that the physical processes are being modelled realistically.
