Abstract
The present work investigates the applicability of scaling log-laws to the turbulent impinging jet. Both, the velocity and the temperature fields are studied under this assumption. To validate the proposed expressions, a detailed experimental program was carried out based on thermal anemometry. The experiments were conducted for one nozzle-to-plate spacing (H/D = 2.0) and Reynolds number of 35,000. A constant wall heat flux condition was achieved by conducting electricity through thin resistors that were placed beneath an aluminum disk. Measurements of local velocity and of temperature distributions are presented as well as longitudinal turbulence profiles. The mean temperature profiles were measured through thermocouples.
