摘　　要：用内燃法热处理大型球罐时,为了减小球罐上下的温差,在球罐内部加入一个V形导流伞,改变球罐内流场分布,使热空气对球罐加热更均匀。采用数值模拟的方法,研究了V形导流伞夹角的角度和导流伞的位置对球罐内部流场和壁面温度的影响。结果表明,在距下人孔1/3球罐直径处安装夹角为120°的V形导流伞时,球罐壁面最大温差最小,球罐壁面温度最均匀。In order to reduce the difference between high and low wall temperatures of the spherical tank when having the internal combustion heat treatment applied there,a V-type diversion umbrella was adopted in the spherical tank to change its internal flow field distribution so that spherical tank＇s wall can be heated more evenly by hot air. Numerical simulation based on Fluent software was carried out to investigate the V-diversion umbrella＇s effect on both internal flow field and wall temperatures of this spherical tank. The results show that installing V-type diversion umbrella at an included angle of 120° at the site 1 /3 of the diameter to spherical tank＇s bottom manhole can make tank wall＇s temperature difference minimum and the wall temperature most uniform.
