Gu and O’Neal [115] proposed an equivalent diameter method as the analytical expression for investigating the steady-state vertical BHE thermal resistances. Fig. 3 presents the transform process based on the assumption that one pipe is concentric within an infinite composite region. This approach ...
aAn extra length per bend is calculated as per tablea, line 3, which is added to the length of pipe used for fabrication of bends. This extra length is valid for bends up to R = 6 D; above this value, the extra length is equal to the lengthmeasured along bend centre line. 额外长...
For the type of the surfaces physically similar to the sand-grain in Nikuradse's experiment, the length scale can be described by the sand-grain roughness height. However, when the shape of roughness deviates from the sand-grain, a single parameter cannot describe the sand-grain roughness ...
