摘要： 熔喷双槽形喷嘴气槽出口处宽度方向上的气体速度分布均匀性受内部气流通道结构的影响。为探究喷嘴内部通道结构对气体速度分布均匀性的影响，采用数值模拟的方式对喷嘴内部气流通道的气体流场进行数值计算。用ANSYS软件中的Workbench平台建立出贴合实际的三维流场模型，并划分出符合网格质量要求的网格。在Fluent软件中设置求解器类型及定义边界条件，进行数值计算。结果表明：气体在由气腔1流入通气孔A时，在通气孔A1至A4出口处的速度峰值及温度谷值各有不同，分布趋势表现为越靠近喷嘴外侧的气孔出口处速度峰值越大、温度谷值越小，越靠近喷嘴中部的气孔出口处速度峰值越小、温度谷值越大。且通气孔B出口处的速度峰值及温度谷值受通气孔A的影响，也呈现出与通气孔A出口处相同的分布趋势。
