Simple high-resolution upwind scheme
Webbresolution, and arti—cial heating takes place. On the other hand, upwind schemes achieve shock capturing and local-ized high resolution in a natural way. When discontinuous solutions are of main interest, second-order (in time and space) schemes are usually adopted, since they reconcile resolution with efficiency and stability needs. However, in Webbthe upwind schemes on several test problems based on Buckley-Leverett equation and discuss the results. Finally, a parallel version of central-upwind scheme in 2D is …

WebbWind speed had the strongest effect on PM during the bus trips, with an increase in 1 ms−1 leading to a decrease in 2.25, 2.90 and 4.98 μgm−3 of PM1, PM2.5 and PM10, respectively. PM2.5 and PM10 concentrations in car trips were better explained by ambient concentrations with high temporal resolution although from a single monitoring station.

These schemes are compared with existing HLL type and Roe type schemes for MHD equations in a series of numerical experiments. These tests reveal that the proposed schemes are robust and have a greater numerical resolution than HLL type solvers, particularly in several space dimensions.
