摘要:
利用有限元软件ANSYS创建法兰连接系统的三维温度场模型，建立螺栓、法兰、垫片间的接触对.设置边界条件及对流传热系数，研究了500 ℃高温条件下炼化装置中法兰连接系统的温度场及热流，并分析了法兰、螺栓、螺纹、螺母、垫片、空气柱的温度分布规律及具体温度值.结果表明：法兰温度从内壁面到外壁面逐渐降低，靠近螺母端外侧温度最低为334.952 ℃；螺栓温度从两端到中间呈现为先增大后减小的规律，螺栓内外侧温差最大值在螺栓的两端；垫片温度沿周向变化很小，垫片温度沿径向由内到外呈线性减小；上、下两段空气柱的温度关于垫片中面对称分布，靠近垫片端内侧温度最高.
Abstract:
a three dimensional temperature field model of flanged connection system was built by the finite element software ANSYS, establishing the contact effect of bolt, flange and gasket. Setting the boundary conditions and the convective heat transfer coefficients, the temperature field and heat flux of flanged joint system in refining device at 500 ℃ were researched. The temperature distribution and the temperature values of flange, bolts, thread, nut, gasket and the air column were investigated. The results show that flange temperature reduces from the inner surface to the outer surface gradually, the lowest temperature is 334.952 ℃ at the outside of the nut end; the bolt temperature increases first, then decreases regularity from the two ends to the middle, and the maximum temperature difference between the inside bolt and outside appears at the two ends of bolt; the gasket temperature along the circumferential direction changes a little, however the gasket temperature along radial direction decreases linearly; the temperatures of the two air column distribute symmetrically along the middle of gasket, and the highest temperature appears at inside surface of air column near to gasket.
