Note that near the area of the strongest winds, the rapidly rotating wind field moves over new patches of the ocean, in a perpetual state of young wave generation corresponding to the cluster of relative low values of the exchange coefficient
for momentum (Cd).
As the cation exchange coefficient
is one of the primary factors governing the rate of cation exchange in HYDRUS (Reading et al.
In this work, we are interested in this part of the calculation of the heat exchange coefficient
Many heat exchangers in a variety of methods are equipped with exchange surface specifically designed to present a higher heat exchange coefficient
and in particular higher than smooth surfaces.
(7.) The Heat Exchange Coefficient
, see Ref, was set to 10.
where Nu is a dimensionless group called Nusselt criterion; C, n, m, p are coefficients; [Pr.sub.0], [Pr.sub.s] are Prandtl numbers correspondingly for cooling medium and cooling surface; [Gr.sub.0] is Grashof number for cooling medium; [Re.sub.0] is Reynolds criterion for cooling medium; [alpha] is value of heat exchange coefficient
which is average for the exposed surface W/[m.sup.2][degrees]C; l is characteristic dimension, m; [lambda] is medium's coefficient of heat conductivity W/m[degrees]C.
The two faces exchange heat with the environment at temperature [T.sub.cnv] with a different heat exchange coefficient
on the upper and the lower boundaries, respectively, [h.sub.u] and [h.sub.l].
The model results are referred to an overall heat exchange coefficient
U = 5 W [m.sup.-2] K.
[[??].sub.dem] is the demagnetization field, [[??].sub.ext] is the external magnetic field, and the interface coupling [A.sub.I] is assumed to be equal to the exchange coefficient
However, the main reason to use TABS is the need for cooling as most of the heat exchange is over the ceiling where the internal heat exchange coefficient
is highest compared to other surfaces (ISO 11855-2).
The exchange coefficient
derived from these valuations is 14.7 (6% below the coefficient announced by RusHydro).
