一种多孔材料对流传热与压降的瞬态测量装置
摘要：
一种多孔材料对流传热与压降的瞬态测量装置，涉及一种多孔材料对流传热与压降的瞬态测量装置。本发明是为了解决目前气体通过多孔材料时压降和换热效果的瞬态试验数据难以保证分析的可靠性的技术问题。本发明由气源、气体流量计、加热器、多孔测试段组成；所述的多孔测试段由压差表、绝对压力表、热电偶、导压管和圆形管路组成；在法兰之间且靠近法兰处各设置一个导压管，两个导压管之间再连通一个设置有压差表的导压管，在法兰和导压管之间的管路内设置热电偶，在导压管之间的圆形管路的管壁设置热电偶。本发明优点：本发明组装方便，待测的多孔材料更换方便，可以测量不同气体工质通过不同多孔材料在一定来流温度和速度的传热和压降瞬时数据。
摘要（英）：

The invention relates to a transient measurement apparatus for convective heat transfer and pressure drop in a porous material and aims to solve the technical problem that presently transient measurement data for pressure drop and heat transfer effect while gas passes through a porous material has difficulty ensuring analytical reliability. The apparatus comprises a gas source, a gas flow meter, a heater, a heater and a porous test segment; the multi-pore test segment is composed of a differential pressure gauge, absolute pressure gauges, thermocouples, impulse tubes and a circular line. Every impulse tube is disposed between two flanges and is close to one flange; another impulse tube with the differential pressure gauge is communicated between the two impulse tubes; multiple thermocouples are disposed in the line between the flanges and the two impulse tubes; multiple thermocouples are disposed on the wall of the circular line between the two impulse tubes. The transient measurement apparatus is convenient to assemble, the porous material to be detected is convenient to change, and the transient measurement apparatus is available for measuring heat transfer and pressure drop transient data while different gas mediums pass through different porous materials under certain incoming flow temperature and speed.
