Dimensionless multiplier correcting the conductive Heat Transfer Coefficient to account for the Natural Thermal Convection effects in the Annulus:
| (1) | U = \cdot \frac{ \lambda}{d_{in} \cdot \ln \frac{d_{in}}{d_{out}} } |
where
\lambda_a | thermal conductivity of fluid |
d_{in} | inner pipe |
d_{out} | outer pipe |
