| Abstract: | The Re （Reynolds number） was introduced in the paper with the expression, the critical value and the application. The application of Re on flow resistance, heat transfer coefficient, absorption coefficient, particle settling velocity, the fluidized bed and the design of air dryer were summarized. The results indicated that Re in different application field, the expression and the critical value is different. So Re should be treated differently, and used according to the particular case. |
