In response to the increasingly stringent cooling requirements of turbine disc and mortise structure, an SATES (self-adaptive turbulence eddy simulation) model was employed to conduct a numerical simulation study on the “S”-shaped gap flow channels generated during the assembly of the turbine disk tenon groove and blade tenon head. The differences in flow characteristics between this channel and a conventional rectangular channel under the same operating conditions were compared and analyzed. The variation of the average wall Nusselt number with the inlet Reynolds number and the rotational Reynolds number under transient conditions in the “S”-shaped channel was investigated. Results indicated that the complex flow structure of the “S”-shaped channel led to a significantly stronger heat transfer capability compared with the rectangular channel. Under rotating conditions, the heat transfer coefficients on the two side walls of the “S”-shaped channel exhibited asymmetry. In contrast to the symmetric distribution observed in the rectangular channel, the heat transfer capability of the right-side wall in the “S”-shaped channel was significantly higher than that of the left-side wall. The average wall Nusselt number on the inner walls of both channels increased with the rise of the main flow Reynolds number and the rotational Reynolds number.
