Our method is based on an underlying uniform Cartesian grid and second-order finite-difference/finite-volume discretizations of the streamfunction-vorticity equations.
The second (90-m grid) and third (30-m grid) areas encompassed 32 × 32 and 13.5 × 13.5 km2 covering Lanyu Island.
Two approaches were adopted to modify the inflow conditions: first, the inflow turbulence intensity was increased by two different rectangular grids and second, the inflow velocity profile was changed to an asymmetric characteristic by two grids with a distinct bar stacking.
A system of Ni+Ng equations in Ni+Ng unknowns is obtained by finite difference discretization on the Ni internal grid points, and second order interpolation to define the conditions for the Ng ghost values.
The resulting schemes have fourth order accurate local truncation error on uniform grids and third order in the non-uniform case.
Second- or fourth-order gradient accuracy can be obtained on regular grids, and first-order accuracy, which is sufficient for second-order finite-volume schemes, can be obtained on irregular grids.
The efficiency of a given method must take in account two basic aspects: the first is the agreement of the results obtained with the coarse grid when compared to the results obtained with the fine grid and the second is the upscaling computational performance.
Alonso, meanwhile, did everything he could to remain in contention, starting from seventh on the grid and finishing third.
Michael Schumacher started third on the grid and finished seventh in a strong race which had the German driver outperforming his teammate — Nico Rosberg, another German, who finished 10th — for the third race in a row.
reports around 750 minor "events" every year, classifying them according to an established grid, and a third are subsequently upgraded to a more serious level because they are recurrent, Mr. Wiroth said.
Most of the global population are not connected to the electrical grid and one third of these people have no access to potable water sources at the same time.
