Abstract:

A technique was developed to enable the evaluation of the correlation between velocity and temperature, with LDA as the source of velocity signals and fine wire thermocouple as that of flow temperature. The discontinuous nature of LDA signal require a special technique for the correlation, in particular when few seeding particles are present in the flow. The thermocouple signal was analog compensated in frequency and the effect of the value of time constant on the velocity temperature correlation was studied.
