Abstract

By determining velocity field inside fresh gases of premixed flame submitted at a sinusoidal perturbation of both high intensity and high frequency, it has been observed a measurement bias by processing the information coming from the analog output of LDV counters. After the evidence is put in this velocity bias by different measurements: average, RMS, FFT and histograms, the attention is focused on instantaneous velocity signal and particularly on the seeding behavior. An explanation of the bias is proposed and also some ideas to control it.
