Atomic Layer Thermopiles (ALTP) are heat flux gauges capable of measuring wall fluxes in challenging high-enthalpy environments. The ALTP combines a high-frequency resolution up to theMHz-range with linear characteristic over several orders magnitude. In the scope this work, new generation ALTPs reduced film thicknesses investigated for its step response behavior moving shock wave, including amplitude-frequency at Small Shock Tube facility Universität der Bundeswehr München (UniBwM).
Abstract This study demonstrates a new methodology for the simultaneous direct measurement of temperature and heat flux within same sensing element sensors. The is demonstrated fast-response atomic layer thermopile (ALTP) sensors makes use temperature–resistance correlation. enables an inherent comparison validation density signal ALTPs. Good agreement found based on experiments in stagnation point subsonic hot air jet. results mainly convective densities are compared against standard...
In this study a fast-response Atomic Layer Thermopile (ALTP) based heat flux measurement system is used for wall heat-flux determination in the combustion chamber of commercially available SI-gasoline engine. The ALTP provides further process variables that supplement conventional cylinder pressure data with are highly resolved time and location. newly developed sensor modules were precisely calibrated compared other techniques radiation- convection-based procedures. Quantitative...
Abstract In this study, the static calibration of different heat flux sensors in radiation- and convection-based procedures are compared. First, three based on principles: ALTP (based Transverse Seebeck Effect), HFM8E (differential-layer device) a TG-2000 (circular-foil gage) calibrated laser-based radiation setup compared to manufacturers calibration. second step, all with standard temperature-based, robust measurement techniques (coaxial thermocouple slug-calorimeter) within newly built...
