盐水溶液模拟非等温室内气流组织的试验研究

Test of Salt Liquor Simulating Non-isothermal Indoor Air-flow

在自行设计和建立的模型实验台上,利用盐水溶液在清水中的扩散运动模拟非等温室内气流组织,并将用CFD的计算结果与实验结果进行了比较。结果表明,模型实验与数值计算的流线图吻合得很好、速度矢量图形状比较一致,可有望用这一方法模拟室内非等温送风的温度场分布。

A series of experiments of using the salt liquor diffusion motion in the water to simulate non-isothermal indoor air-flow was carried out. The author used PIV to test experiment result and compares CFD result with experiment result. The result showed that the model test agrees well with numerical simulation. It is a feasible moled test method.
