| Abstract: | Heat transfer in a transverse corrugated tube using molten salt as working fluid is investigated.The influence of heat transfer by temperature and thermal flux is investigated.The heat transfer characteristics are compared with those in a smooth pipe,and the range and approach of enhanced mechanism are discussed.The results show that the heat transfer of transverse corrugated tube is better than that in smooth tube. |
| Keywords: | transverse corrugated tube molten salt enhanced heat transfer |
