![]() ![]() A ridged socle with triangular extensions forms the base of this grave marker and would have been contiguous with the rectangular lid of the tomb. The center section, bordered at right and left by vertical bands of simple interlace, contains a short inscription band and, below it, four rows of four hexagons containing crosses. The latter motif is repeated twice in a band below the arches. On either side of the wider central section are two arches with a scallop design in the arch, below which a vine in the form of a stylized leaf encloses a trefoil. Each of the long sides has three sections. While the limestone grave covers of this type from Siraf are decorated with elaborate kufic inscriptions, most of the ornament on this piece is geometric and vegetal. Extant examples of such tombstones range in date from the late tenth to the early thirteenth century. It is observed that the magnitudes of Reynolds stresses in the near wake region are an order higher in the AR1 case than in the AR4 case.Tombstone This stone in the form of a small sarcophagus would have been attached to a larger lid of a grave marker. One-dimensional profiles are used to quantitatively assess the differences in the flow characteristics. ![]() Mean flow reattaches over the prism in the AR4 case, but there is no reattachment in the AR1. However, the mean recirculation bubbles over the prism and in the wake region show significant differences. The results show that mean flow separation at the leading edge is not affected by the different geometries and the streamwise aspect ratios. The effects of aspect ratio on the mean flow, Reynolds stresses and third-order moments were investigated, and the results were compared with a square prism. The Reynolds number based on the prism height and the freestream velocity was 14700. The tested streamwise aspect ratios (AR) based on the height and upper surface were 1 and 4. The shear layer and the near wake region of right trapezoidal prisms with varying streamwise aspect ratios in a uniform flow were investigated using particle image velocimetry.
