在许多应用中，工程师都会遇到空气混合问题。中央空调系统、汽车中的HVAC模块、发电系统中的磨煤机、车辆中的发动机燃烧系统和通风管道就是此类应用的几个例子。大量关于气流混合的实验和计算流体动力学（CFD）研究已经在公开文献中进行并报告。速度和温度测量以及流动可视化方法被用于研究气流的混合。此外，一些CFD方法已被应用于模拟气流混合和混合箱中的发展。 进行了有关空气混合和相关系统的文献调查。调查集中在五个主题上:（1）混合箱中气流模式的模拟和测量（2）混合箱中的分层问题（3）空气阻尼器控制特性（4）空气混合箱（5）空气混合增强方法研究人员随后制定了一个测试计划，包括测试配置、实验设施、仪器和测试程序。

Air mixing problems are encountered by engineers in many applications. Central air conditioning systems, HVAC modules in automobiles, pulverizer mill of power generating systems, engine combustion systems in vehicles, and ventilating ducts to mention are a few examples of such applications. A great deal of experimental and computational fluids dynamics (CFD) studies of airflow mixing have been conducted and reported in the open literature. Velocity and temperature measurements and flow visualization methods were applied to investigate mixing of airflows. Further, several CFD methods have been applied to simulate airflow mixing and developments in the mixing boxes.A literature survey pertaining to air mixing and associated systems was been conducted. The survey focused on five topics:(1) Simulation and measurement of airflow patterns in mixing boxes(2) Stratification problems in mixing boxes(3) Air damper control characteristics(4) Air mixing boxes(5) Methods for air mixing enhancementThe researchers then developed a test plan consisting of the configuration tested, an experimental facility, instrumentation, and test procedures.
