摘要
根据某逆流(3D FEM)式自然通风冷却塔的设计资料,按照三维有限元计算理论,采用热-力耦合场分析技术,计算冬季运行工况下由线性温度场引起的温度应力和夏季日照工况下由非线性温度场引起的温度应力,可为冷却塔的设计提供参考依据.
Adopted technique of temperature field and stress field accouplement,it analyzed the thermal stress under the effect of linear temperature field in winter and nonlinear temperature field in summer based the design data of a natural draft cooling tower and the 3D FEM.It provides the consult for design of the cooling tower.
