Numerical Prediction of Wind Flow over Sinusoidal Hills Using Multigrid Method

Abstract:

The finite volume method and multigrid method are presented to solve Navier-Stokes equations. MG method is introduced in this work and applied on solving the discrete systems of the governing equations. For turbulent flow, the standard k-ε model is adopted. The non-orthogonal collocated grid systems are generated. The numerical prediction were done for the flow over sinusoidal hills. The numerical results were obtained from the simulations of flow over three types of sinusoidal hills. Comparisons have been made between experimental data and the computational data and agree with each other.
