Data on distribution of heat transfer coefficient and profiles of velocity and turbulent characteristics behind a rib in pulsating flows
Raw experimental data on heat transfer from the wall are presented in the form of electric signals (voltage in V). The data were collected from 42 measurement tracks; 1 reference resistor 226 Ω in the temperature measurement circuit with a resistance thermometer UTR; 1 signal from resistance thermometer UT; 4 signals from 4 reference resistors 5 Ω in circuits of measurement elements UR 10 1 - UR 10 4. Measurement elements Ri corresponded to the following channels: - R1 – R10 – channels 32 to 23; - R11 – R26 – channels 48 to 33; - R27 – R42 – channels 16 to 1; - UT – channel 17; - UTR – channel 20; - UR 10 1 – UR 10 4 – channels 18, 19, 21, 22. Elements R1 – R42 were placed on the wall with a streamwise spacing of 9.5 mm. Voltage drop measured across the reference resistors yielded the magnitude of electric current in the respective circuits. Each file contains the data for one regime of air flow. File names specify the volumetric flow rate (Q, m3/h) and forcing frequency (f, Hz). R0i file contains signals for estimation of reference resistances of measurement elements at 23°С.
