Title: Proposal for wall function for friction and heat transfer in the presence of roughness and mass transfer
Abstract: Abstract The heat transfer characteristics are predicted of a turbulent boundary layer over a rough porous wall through which mass is injected. A proposal is made for the wall function that accounts for the simultaneous influences of roughness and mass transfer. This proposal though has no strong theoretical foundation, appears justified by agreement with experiment. The problems considered include cases with and without unheated lengths of plate. The separate effect of roughness without mass transfer is also investigated. The predictions compare well with the measurements of Coleman et al. for uniform-grain elements under fully rough conditions.
