Details
The Sherwood number depends on a combination how much free or forced convection predominates. For mixed convection:
Sh = (a Re ^ b) ^ {3.5} + (c Gr ^ d) ^ {3.5}) ^ {1 / 3.5}
Symbol | R | Description | Units | Default |
a, b, c, d | a, b, c, d | empirical coefficients | none | calculated |
Gr | Gr | Grashof number | none | calculated |
Re | Re | Reynolds number | none | calculated |
Value
A unitless number of class units
