The Nusselt numbers
are found from the correlations given in (4) for each surfaces.
The current work concentrates on understanding the scaling that influences the creation of these two distinct regions, and the development of predictive correlations for both friction factors and Nusselt numbers
Generally, the main sources of errors in results of the Nusselt numbers
are statistical uncertainty of surface mean-temperatures and bulk temperature of the fluid.
The performance of these jets is evaluated in terms of the measured increases in the values of the local Nusselt numbers
and the uniformity of their radial distributions on the impinged surface.
Laminar flow regimes in the peripheral pipes giving constant Nusselt numbers
and almost constant heat transfer coefficients make the average borehole thermal resistance of the multi-pipe design vary very little with the flow rate.
In the laminar region of Reynolds number investigated, the measured local Nusselt numbers
agreed with classical developing flow theory.
The dimensionless Nusselt numbers
on the non-insulated boundary walls of the triangular duct are calculated using the formula.
Extensive results elucidating the effect of Brinkman, Reynolds and Prandtl numbers on the local and surface-averaged Nusselt numbers
are presented and discussed herein.
Profiles of Nusselt numbers
as a function of Ra were developed for various dome shapes.
Note that at the lower Nusselt numbers
there was a large deviation in the data.
4 shows the distribution of local Nusselt numbers
for various Reynolds number at H/d = 4.
At high Nusselt numbers
, heat transfer between the resin and preform dominates.
