STAR-CD a CFD code was used to predict airflow and pressure
distribution in the duct/leaks geometry described above and over
a range of Reynolds numbers between 27,000 and 82,000 to gain
a better parametric understanding of the relationship between
leakage flow and pressure drop across these leaks. Six generic
geometries of leaks were used i.e. square, rectangular, circular and
elliptical shapes were simulated. This section deals with the results
of these simulations and their comparisons in certain cases to previously
published work.
