考虑近壁区域分子粘性的置换通风数值模拟
Numerical Simulation of Airflow with Displacement Ventilation When Thinking of Molecular Mucosity near Wall
【摘要】 采用K ε两方程模型对置换通风气流组织进行数值模拟 ,其中在壁面附近的粘性支层中采用壁面函数法 ,并对气流组织的速度场和温度场进行可视化处理 .分析置换通风方式在空态和室内有障碍物时气流组织的异同点 ,为研究置换通风方式的特点提供参考
【Abstract】 Adopting K?ε double-equation,simulating airflow organization with displacement ventilation,adopting wall function method when calculating dauby branch layer,using figure show its velocity field and temperature field,This paper analyzes the similarities and differences between vacant state and state with stumbling block indoor,and offers reference for studing characteristics of displacement ventilation.
