摘要/Abstract

摘要： 对伞蜥这一有特殊散热结构的爬行动物进行物理建模，并对该模型展开自然对流传热特性的数值研究。研究发现，调节模拟伞蜥颈部褶皱的不同张角(45°~85°)时，换热系数在65°附近达到唯一最大值。同时改变伞蜥颈部褶皱的大小，显示对流传热系数的唯一最大值出现在6.3≤ L₀/d ≤6.6范围内，模拟得到的最大传热速率对应的张角和面积均接近选取亚种的自然状态，由此推测伞蜥颈部褶皱的进化方向可能朝有利于提高自然对流传热速率的方向进行，而伞蜥与外界环境的自然对流可能是影响伞蜥颈部褶皱进化方向的重要原因之一。

Abstract: In this paper, the physical modeling of frill-neck lizard, a reptile with special heat dissipation structure, was carried out, and the natural convection heat transfer properties of it were numerically studied. It was found that there was only one maximum heat transfer coefficient in the range of 45°-85°, which was obtained at around 65° for the simulation of different field angle adjustments of frill-neck lizard neck fold. At the same time, by changing the size of frill-neck lizard neck fold, it was also observed that there was a unique maximum convection heat transfer coefficient in the range of 6.3≤ L₀/d ≤6.6. In addition, the field angle and area corresponding to the maximum heat transfer rate were close to the natural state of Australian subspecies. Therefore, it can be inferred that the evolution direction of frill-neck lizard neck fold may be beneficial to improving the natural convection heat transfer rate. Hence, the natural convection between frill-neck lizard and external environment may be considered as an important reason affecting the evolution direction of Chlamydosaurus kingii neck fold.

Key words: neck folds of the frill-neck lizard, natural convection, $\overline{N u}$ number, numerical simulation
