Subisokinetic Sampling Errors For Aircraft Turbine Engine Smoke Probes.
Abstract
Experimental evidence that isokinetic sampling can be important for submicrometer particles in high speed flows was presented in CEEDO-TR-77-48. This report applies those results to gas turbine engine smoke measurement. The analysis predicts a 15 to 30 percent subisokinetic sampling error at a take-off engine power setting. It is concluded that subisokinetic errors do not greatly affect smoke number determinations but should be considered when true smoke density is measured. (Author)
