| Summary: | 10-15% for the forward rotation, and decreases by 10-18% for 2,500 to 12,500. The isolated effects of Rej, and rotating average Nusselt numbers show reasonable agreement when blades. compared with previously reported correlations. The pressure cross flow at the end of the channel. The results also show decreases slightly with an increase in cross flow for both distributions in the channel are recorded before and after distributions show that the major effect on heat transfer is heat transfer in a two-pass rotating rectangular channel is impingement. The experimental results show that the Nusselt number increases with an increase in jet Reynolds number and of multiple, staggered array, round impinging air jets are on the trailing wall (radially outward) and on the leading performed to determine the influence of jet impingement on presented. The jet rotation number (Ro) is varied from 0.0 radially outward and inward flow. The Nusselt number is high rotation (Coriolis and centrifugal forces). This study was speed (D = 0, 400, and 800 rpm), are measured. The pressure studied. The results of an experimental investigation on the surface heat transfer coefficients under a perforated plate that heat transfer at high rotation numbers increases up to The combined effects of rotation and jet impingement on local the cooling of turbine blades under rotating conditions. the jet impingement in the beginning of the channel and the the reverse rotation when compared with stationary results. These results can be applied to cooling design of gas turbine This is due to the secondary flow induced in the channel by to 0.0226, and the jet Reynolds number (Rej) is varied from wall (radially inward) for forward rotation.
