In order to clarify the effect of area ratio of the first bend on the flow heat transfer and structural response of serpentine nozzle, the effect of the thermal-solid coupling response under different area ratios of the first bend was investigated using the serial two-way loose coupling method based on the multi-physics coupling analysis software MPCCI (mesh-based parallel code coupling interface). Results were obtained as follows: the overall heatflux distribution of the nozzle under the action of large curvature and multi-bend structure was non-uniform, while the heatflux distribution of nozzles was similar; the strongest heat transfer occurred at the first bend of different nozzles, and with the increase of the outlet area ratio of the first bend, the heat flux at the first bend decreased gradually; the vortex structure was generated at the exit isometric section, making the heat transfer blocked. In structural stress response, the maximum stresses of all nozzles appeared at the exit end of the upper wall. Serpentine nozzle with the first bend outlet area ratio of 0.8 at
