| Abstract: | An investigation is
made on the applicability of method of representing by Cartesian grid to
calculate flow over natural terrain. Model hill geometry with different maximum
slope angles is chosen and calculations by both Cartesian and Boundary-fitted
coordinate representations are made. Computations are performed for laminar
flow at different Reynolds numbers and turbulent flow conditions. Results in
terms of mean velocity distribution, streamline, vorticity distribution and
velocity vector close to the surface are analyzed and discussed. The study
indicates that to calculate flow over undulating natural terrain, rectangular
coordinate method of representing the geometry is able to capture most of the
flow phenomena and it can be a viable alternative. |
