摘　　要：为研究场协同原理对气流场温度均匀化的适用性,设计了一个温差可控并能形成具有梯度的气流速度场与温度场的加热器,然后在加热器整流区内布置3种特殊的整流网,利用Fluent进行三维数值模拟。结果表明,场协同原理对于提高气流场温度的均匀性是有效的,并依此原理提出了气流场温度均匀化的最佳方法。For cognition of the essence of convective heat transfer is not unified for long time,so temperature homogenization method of air current field in chamber is shorting of uniform and effective theory to guide.In order to research the applicability of field-synergy principle,a temperature gap controlled heater is designed,which can form a temperature gradient field and velocity gradient field.At the bottom of the heater,3 special devices are installed.For the air current field in the chamber,3D simulation is carried out by Fluent.The results show field-synergy principle is validate to enhance the temperature homogenization.Following the principle,the best way to improve temperature field homogenization is proposed.
