Numerical prediction of indoor airflows by means of the K- epsilon turbulence model

Describes the current status of numerical prediction of indoor turbulent flows in elementary and complicated room geometries using the K- epsilon two-equation model of turbulence. Predictions are compared with available experimental results, and the applicability of the method is demonstrated under isothermal and nonisothermal conditions. Exploratory applications for complicated flow conditions intended to assess its relevance to practical ventilation problems are presented. Possible modifications to the method are discussed. Recent work to develop an efficient solution algorithm to obtain steady-state solution with small computational time is reviewed. (from authors' abstract)
