Abstract

This article presents the results of temperature measurements in a real model of heat exchanger using LIF method. By the help of fluorescent dye Rhodamine B that responsive on the temperature variation is visualized the rate and warming - up of the liquid above the heating pipe. The drift excited by heat convection is measured by PIV method. The results of temperature field measurements are compared with metering affected by temperature probe.
