学校计算机房室内气流分布的数值模拟

Mumerical Simulation of Airflow Distribution is a Computer Room

运用k -ε紊流模型对学校计算机房 (学生机房 )室内气流组织 ,主要是速度场的温度场进行了数值模拟 .采用有限单元法和交错网格 ,将人体散热和设备散热及围护结构得热作为能量方程的附加源项 .求解了计算机房室内空气流动与传热问题 。

By K-ε turbulence model,a computer room airflow distribution is simulated,and the velocity and temperature field are solved with finite element method in interlacing grid. The heat of people and equipment and solar radiation are taken into account,and these auxiliary heat flows are the source terms of the energy equation. The air flow and heat transfer problems are calculated in the computer room. A basis is given for the optimized design of air origination in the air-conditioned computer room.
