Mathematical model of Heat Transfer Coefficient through the annulus gap between concentric pipes filled with solid body:
(1) | U = \frac{\lambda}{d_h} \, {\rm Nu} |
where
\lambda | thermal conductivity of flowing fluid |
d_h | annular hydraulic diameter |
\rm Nu | dimensionless Nusselt number (Nu) |
