Development of software for thermal-hydraulic simulation and verification calculation of shell-and-tube heat exchangers
摘要
Abstract
With the strategic adjustment and demand of the national energy structure,the pivotal role of heat exchangers in energy systems has become increasingly prominent.Consequently,higher requirements have been put forward for the accuracy,intelligence,and reliability of their design and calculation.This paper focuses on shell-and-tube heat exchangers,which are widely applied in nuclear power systems.Based on the Bell-Delaware flow path analysis model,the global structure of the heat exchanger is reasonably segmented,and an accurate segmented calculation model and method for heat transfer and resistance of shell-and-tube heat exchangers are established.Furthermore,an accurate and intelligent software for verification and simulation calculation of shell-and-tube heat exchangers is developed using Python programming language,which can also realize the functions of series arrangement design and tube layout design of heat exchangers.Verification and simulation analysis are conducted on six engineering cases of E-type and F-type shell-and-tube heat exchangers respectively.Compared with the calculation results of HTRI,an internationally mainstream software,the deviation of the total heat transfer coefficient is less than 10%,and the deviation of the shell-side pressure drop is less than 22%.These results indicate that the developed software can accurately calculate and evaluate the heat transfer performance and resistance performance of shell-and-tube heat exchangers,and is worthy of further popularization and application.关键词
