Estimation of the error of temperature compensation of one class of thermoanemometer
Abstract
The transfer function of temperature-compensation error is determined for a thermoanemometer; compensation is carried out by high-speed voltage-regulated resistors. Calculations are performed on the basis of a linear model of the thermoanemometer as a system with quasi-constant parameters excited by temperature fluctuations in the form of a harmonic function of time. Experimental data on the temperature and velocity fluctuations of a nonisothermal air flow serve to confirm theoretical results.
