The calculation of jet interference pressure distribution using integral and numerical methods based on actual measurements of entrainment
Abstract
Factors influencing interference effects on aerodynamic surfaces surrounding jets are discussed. A tracer gas method is used for the measurement of jet entrainment. This technique is applied to the study of axisymmetric free jets. A numerical method is developed which employs measured values of entrainment to compute the interference pressure distribution over a flat surface surrounding the jet. Comparisons are made with theory to show that computational inaccuracies may be reduced to required values.
