| Abstract: | Wholly the theory and its application on temperature boundary layer in laminar flow of contracted pipeline fitting is studied by the paper. Calculation formula of velocity distribution, boundary layer thickness,friction force and loss of water head are given out , in accordance with the result from theory analysis of similitude solution. Based on equation of temperature boundary layer of pipeline, calculation expression of temperature distribution,temperature boundary layer thickness and heat flux of pipeline are deduced. Finally, intact examples of design and application are given out by the paper. |
