Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Thesis / Dissertation Description
The governing partial differential equations of fluid motion are usually numerically approximated using one of the three classical methods: Finite Difference (FD), Finite Volume (FV) or Finite Element (FE). In this thesis, a new cell-centred FD (CCFD) formulation is developed, in which the governing fluid flow equations are differenced over all the cell centres instead of grid points. The nodes (grid points) are then updated by averaging the property from all the cell centres that share that node. This feature, which is motivated by development of the FV method, allows the application of the proposed FD numerical formulation on unstructured grids. Several test cases are investigated here to illustrate this approach. To verify the results, the analytical solution for the test case is used if available. Otherwise, the numerical solution is compared to the traditional FD solution.
