dimensions, grid sensitivity studies were not undertaken for all
cases. The maximum numerical error to be expected in the numerical
calculations of air flow and pressure drop through the air leakage
geometry is estimated as i.e. 2.1% which is the more important
direction of flow i.e. Z in the normal plane to the leak. At this point
no present experimental validation has been done but the authors
feel ample evidence has been provided in Section 2 on the reasonable
accuracy of prediction of this model from previous published
work.
