研究了振动对固流体波面换热器传热特性的影响。结果表明:振动床中温度场的发展明显优于同类条件下移动床中温度场;在频率为23.67Hz和一定流量下,随着振幅在一定范围内增大,其壁面传热系数也增大,有利于床层内物料间的传热。
The influence of vibration on the heat transfer characteristics of solid fluid wave heat exchanger was studied. The results show that the development of temperature field in vibrating bed is obviously better than the temperature field in moving bed under the same conditions. At the frequency of 23.67 Hz and a certain flow rate, the wall heat transfer coefficient increases with the amplitude increasing within a certain range Large, is conducive to heat transfer between the material within the bed.
