On the basis of analyzing the climate performance in the hot summer and warm winter zone,the thermal performance of typical residential building walls in this district is experimented and the coefficient factor of heat transfer and index of thermal inertial are derived by these experimentdata. 在...
hood (2), so that the inner wall of the external heat exchange tube (1) is exposed to the steam to the greatest extent, and a thin liquid film is formed on the inner wall surface of the external heat exchange tube (1), thus improving the condensation heat transfer coefficient. ...
At the end of the computation, I am checking the 'local heat transfer coefficient' at the interface fluid/solid (I have read in the manual that the local definition is used there). I am getting quite high value for the coefficient (around 220 W/m2K) ...
