Some of the settings you can use to get a better mesh are shown in the figure below.
You can insert a sizing for faces and edges along with the mesh settings in the figure.
You can give a bias to edge sizing to cluster cells towards one end of edge. See this page for how to implement a bias to an edge.
Below is a mesh we obtained by playing with these settings. This mesh resolves the separated flow behind the plaque better than the default mesh. It can be further improved though! You could start by changing the "edge sizings" in the left branch.
The following videos show how to plot streamlines using the CFD Post post-processor included in ANSYS Workbench. First, we plot streamlines emanating from the the inlet.

The streamlines emanating from the inlet do not include those in the recirculating region or the "deadwater" region. To see the streamlines in the recirculating region, we:
Plot streamlines emanating from these points
