摘要
Since fuel has been an important heat sink to high speed aircraft, the dynamic thermal analysis of the fuel tank is of more great significance. Relative to some published simulation methods, we tried the dynamic node thermal network analysis method with two new concepts of the twinned tanks and the HTP tie on Sinda/Fluint software to solve the two-phase heat transfer problem caused by the liquid level drops. The compared results to the VOF method on Fluent software for a typical fuel tank problem showed that the method used in this paper can obtain a fairly accurate results and improve the calculation efficiency greatly at the same time.
