Data for: A systematic DNS approach to isolate wall-curvature effects in spatially developing boundary layers

Spanwise [z] and temporal [t] averaged turbulent fields of four direct numerical simulations (DNS) of a turbulent boundary layer (TBL) calculated using the code NS3D. Datasets ZPG-C & ZPG-F both have approximately zero pressure gradient along the wall boundary, whereas PG-C & PG-F have a nearly identical non-zero pressure gradient. Both ZPG-C and PG-C have the same curved (C) wall shape and ZPG-F and PG-F are flat (F) plate TBLs. See publication for a full description of the study design. The data are stored in HDF5 containers in which 2D and 1D datasets are present, along with grid coordinates and characteristic freestream conditions of the cases.
