Numerical simulation of pressure on 2D geometry of TTU test building

摘要

The mean and standard deviation of wind-induced building pressures on two-dimensional geometry of the Texas Tech University (TTU) test building are predicted using numerical simulations. The results obtained from the steady-state numerical calculations are compared with the experimental data obtained for a 1:50 geometrical scale model. Computations were carried out using an in-house-developed computer program (JC-FLOW) and the FLUENT 6 software package Various modifications of the κ-ε turbulence model were employed in simulations carried out using JC-FLOW. Overall, the mean pressure coefficients obtained from numerical tests were in good agreement with the experimental data. For the JC-FLOW, the best agreement was obtained using the RNG κ-ε model. The numerical-laboratory agreement for the pressure standard deviation was good on the leeward wall and on the leeward portion of the roof.
