Abstract:
Several mathematical schemes for calculating ventilation flows and their associated errors using the multiple perfluorocarbon tracer (PFT) method developed at Brookhaven National Laboratory are presented and methods are suggested for their implementation on microcomputer systems. A first order error analysis method is described along with a matrix method which yields identical results but is computationally much faster. Both methods are compared to the Monte Carlo error analysis technique. The computation of an optimal condition number is suggested as a means of gauging the sensitivity of the flow solutions.
