Dynamic behaviour of cold wires in heated airflows (300<T<600 K)

A theoretical and experimental investigation of cold wire frequency response is presented for the case of heated airflows (T less than 600 K). Experiments using an external heating technique have been carried out for sensors in different flow situations. Particular attention has been paid to the inf...

Zusammenfassung:	A theoretical and experimental investigation of cold wire frequency response is presented for the case of heated airflows (T less than 600 K). Experiments using an external heating technique have been carried out for sensors in different flow situations. Particular attention has been paid to the influence of temperature on cold wire transfer function characteristics (time-constant and plateau level).
