To analyze the influences of jet temperature, disk rotating speed, jet flow and disk temperature on the heat transfer of rotating disk, the two-phase flow and heat transfer characteristics of the lubricating oil jets from the twin nozzles impinging on a high-speed rotating disk were studied by numerical simulation. The results showed that the jet temperature increased from 323 K to 423 K, which increased the average Nusselt number by 28.54%. When the rotational speed of the disk surface increased from 4 000 r/min to 10 000 r/min, the average Nusselt number of the surface decreased by 10.61% with the increase of the rotational speed, but the influence of the rotational speed on the effective heat transfer area was limited. Therefore, the average Nusselt number rose again under the condition of 12 000 r/min. The increase of the jet flow rate effectively increased the flow rate of the oil film on the disc. As the jet flow rate increased from 0.5 L/min to 2.5 L/min, the average Nusselt number increased by 152.06%. As the temperature of the disk surface increased from 423 K to 723 K, the heat transfer effect at the same position on the disk surface was significantly enhanced, and the average Nusselt number on the surface increased by 117.34%. Finally, based on the jet Reynolds number, rotational Reynolds number and Prandtl number, the dimensionless correlation of the surface average Nusselt number was established.
