(DOI:10.1007/s00348-021-03353-x) It features experimental and numerical data on two ridge-type geometries specified in figures 1 and 2. The data is provided as .dat files separated for geometries (trapezoidal grooves, rectangular grooves) and for the individual data sources (DNS, PTV, HW, dPdx, PIV). An overview of all provided files is given in table 1. The nomenclature stated in table 1 is the same as introduced in the manuscript in table 1. figure 1: trapezoidal grooves ``` _____s_____ /\ /\ | / \ / \ |h ___/ \_____/ \_|___ ``` | ID | flow type | s/δ | h/δ | tip angle[°] | |-----------------------------------------------|--------------|--------|---------|----------------| | trixx | channel | 2.16 | 0.158 | 54.8 | | trixx | engine | 1.52 | 0.376 | 65 | ______________________________________________________________ figure 2: rectangular grooves ``` _______s______ ____ ____ | | | | | | | | h ___| |_______| |_____ __w__ ``` | ID | flow type | s/δ | h/δ | w/δ | |-----------------------------------------------|--------------|---------|--------|---------| | rectxx | channel | 1.22 | 0.078 | 0.238 | | rectxx | engine | 1.12 | 0.174 | 0.562 | __________________________________________________________ table 1: database case overview | filename | flow type | data source | Reb | Quantities stored | |------------------------------|--------------|-----------------|-----------------|----------------------------------------------------| | | | | | | | refpiston.dat | engine | PTV | 15000 | y,y/d99,z,z/d99,U,V,U/U0,(V-V0)/U0 | | refdns.dat | channel | DNS | 18000 | y/delta,U/U0,uu/U0^2,vv/U0^2, | | | | | | ww/U0^2,uv/U0^2 | | | | | | | | tridpdx.dat | channel | dPdx | 5000-85000 | Reb, Retau, Cf | | trihw12.dat | channel | HW | 12000 | z/delta,y/delta,U/U0 | | trihw18.dat | channel | HW | 17900 | y/delta,z/delta,U/U0,urms/U0 | | trihw37.dat | channel | HW | 37500 | z/delta,y/delta,U/U0 | | trihw58.dat | channel | HW | 58200 | z/delta,y/delta,U/U0 | | tridns.dat | channel | DNS | 18000 | y/delta,z/delta,U/U0,V/U0,W/U0, | | | | | | uu/U0^2,vv/U0^2,ww/U0^2,uv/U0^2, | | | | | | uw/U0^2,vw/U0^2 | | trispiv.dat | channel | sPIV | 18000 | y,z,U,V,W | | tripiston.dat | engine | PTV | 15000 | y,y/d99,z,z/d99,U,V,U/U0,(V-V0)/U0 | | | | | | | | rectdpdx.dat | channel | dPdx | 5000-85000 | Reb, Retau, Cf | | recthw.dat | channel | HW | 18000 | y/delta,z/delta,U/U0,urms/U0 | | rectdns.dat | channel | DNS | 18000 | y/delta,z/delta,U/U0,V/U0,W/U0, | | | | | | uu/U0^2,vv/U0^2,ww/U0^2,uv/U0^2, | | | | | | uw/U0^2,vw/U0^2 | | rectpiston.dat | engine | PTV | 15000 | y,y/d99,z,z/d99,U,V,U/U0,(V-V0)/U0 | ______________________________________________________ PTV: particle tracking velocimetry DNS: direct numerical simulation dPdx: pressure-drop measuremts HW: hot-wire measurements sPIV: stereoscopic particle image velocimetry -------------------------------------------------------------------------------------------- lars.deyn@kit.edu

    Database: Ridge-Type Roughness - From Turbulent Channel Flow to Internal Combustion Engine

    This database provides the data presented in the manuscript "Ridge-type
    roughness – from turbulent channel flow to internal combustion engine".
    (DOI:10.1007/s00348-021-03353-x)
    It features experimental and numerical data on two ridge-type geometries
    specified in figures 1 and 2.
    The data is provided as .dat files separated for geometries (trapezoidal grooves,
    rectangular grooves) and for the individual data sources (DNS, PTV, HW, dPdx, PIV).
    An overview of all provided files is given in table 1. The nomenclature stated in
    table 1 is the same as introduced in the manuscript in table 1.
