本文针对高温氦气在光管及波节管中的传热特性及阻力特性进行了Reynolds Stress Model（RSM）数值模拟研究。比较模拟计算和经验公式的结果，两者基本吻合。比较了Nu和，在波节管和光管中的变化规律，同时，分析了波节管的局部Nu和局部壁面剪切应力Tw沿壁面的变化规律。数值模拟结果表明相同工况下波节管的Nu大于光管，说明波节管具有较强的强化换热能力，同时，波节管的，也有一定增加，但波节管总体性能优于光管。在较大雷诺数下，波节管具有更佳综合性能。
This paper conducts a Reynolds Stress Model (RSM) numerical simulation research on heat transfer characteristics and resistance characteristics of high-temperature helium gas in smooth tube and corrugated tube. The simulation is consistent with the empirical formula. The variations of Nu and f in corrugated tube and smooth tube were compared and the variations of local Nu and the local wall shear stress Tw along wall surface were analyzed. The simulation shows that Nu of corrugated tube is greater than one of smooth tube, which indicates the corrugated tube have more enhanced heat transfer effect, while the f of corrugated tube also increase, however, the overall performance of corrugated tube is better than smooth tube. The overall performance of corrugated tube is more superior in the condition of Reynolds number is lar~er.
