Thermal Statistics of Turbulent Forced Convection Pipe Flow for Azimuthally Inhomogeneous Thermal Boundary Conditions

This database features thermal statistics for fluids of Prandtl numbers Pr=0.71, 0.025 and bulk Reynolds numbers of Re=5300, 11700, 19000, 37700 in a fully-developed forced convection pipe flow.

The wall heat flux is prescribed to be adiabatic on one half of the pipe and constant ("halfconst") or sinusoidal ("halfsin") on the other half.

The detailed description of the numerical setup and discussion of the statistics contained in this database are given in the accompanying publication:
Straub, Forooghi, Marocco, Wetzel, Frohnapfel. "Azimuthally inhomogeneous thermal boundary conditions in turbulent forced convection pipe flow for low to medium Prandtl numbers". International Journal of Heat and Fluid Flow. 2019
