Basic sub-grid obstacle flame-wrinkling enhancement factor model. Details supplied by J Puttock 2/7/06.
Sub-grid flame area generation
\( n = N - \hat{\dwea{\vec{U}}}.n_{s}.\hat{\dwea{\vec{U}}} \) \( n_{r} = \sqrt{n} \)
where:
\( \hat{\dwea{\vec{U}}} = \dwea{\vec{U}} / \vert \dwea{\vec{U}} \vert \)
\( b = \hat{\dwea{\vec{U}}}.B.\hat{\dwea{\vec{U}}} / n_{r} \)
where:
\( B \) is the file "B".
\( N \) is the file "N".
\( n_{s} \) is the file "ns".
The flame area enhancement factor \( \Xi_{sub} \) is expected to approach:
\[ \Xi_{{sub}_{eq}} = 1 + max(2.2 \sqrt{b}, min(0.34 \frac{\vert \dwea{\vec{U}} \vert}{{\vec{U}}^{'}}, 1.6)) \times min(\frac{n}{4}, 1) \]
