COMPUTATION OF FLOW AROUND TEXAS-TECH BUILDING USING K-EPSILON AND KATO-LAUNDER K-EPSILON TURBULENCE MODEL

An efficient model F3Dk epsilon has been developed using a preconditio ned conjugate gradient procedure to solve the pressure correction equa tion. It is eight times faster than the work presented by R.P. Selvam (J. Wind Engng Indust. Aerodyn. 1992, 41-44, 1619-1627) and more than 16 times faster than explicit procedures, Using this code, the flow ar ound the Texas Tech building is computed using the k-epsilon and Kato- Launder k-epsilon turbulence models. The computed pressures are compar ed with existing experimental results. The computed turbulent kinetic energy from the Kato-Launder k-epsilon model is compared with that fro m the regular k-epsilon model. Copyright (C) 1996 Elsevier Science Ltd .
