Passive-scalar transfer-kernel modelling for thermal transit-time flow measurement in pipe flow

Abstract Thermal transit-time flowmeters are attractive for high-temperature, corrosive and irradiating environments, but the usual single-delay relation U = L/τ does not represent the effects of velocity-profile shear, radial scalar mixing, finite thermocouple response and channel mismatch. This study develops and tes...
