... of heating power and placement angle on the start-up time, isothermal performance, and heat transfer performance of the test piece are studied by experiments. The increase in heating power is helpful to shorten the start-up time and improve the isothermal performance and heat transfer performance of the test...

... temperature is more uniform to avoid the occurrence of concentrated high-temperature areas. With the Reynolds number changing from 1000 to 1750, the heat transfer performance of the three-dimensional topology-optimized structure increases by 16.79% to 20.82%. The overall design domain of the simplified...

... n ( ∂ Y ∂ X i ) 2 U 2 ( X i ) where U ( Y ) is the standard uncertainty of X i . Uncertainty of experimental study on heat transfer performance of CO 2 falling film evaporator is analyzed. In this article, the class B uncertainty method is used...

... is available to drain the hot end of the heat pipe, and the installation method of the cold end has an important influence on heat transfer. For this reason, a detailed experimental study of heat transfer performance was carried out in this paper. It is found that: there is a capillary lifting force...
