RESPONSE OF HOMOGENEOUS AND TWO-MATERIAL LAMINATED CYLINDERS TO SINUSOIDAL ENVIRONMENTAL TEMPERATURE CHANGE, WITH APPLICATIONS TO HOT-WIRE ANEMOMETRY AND THERMOCOUPLE PYROMETRY

摘要

In current aeronautical research, rapidly responding thermocouples and hot-wire anemometers are required A laminated cylinder consisting of an oxide rode and thin metallic coating is known to provide a larger output signal than a conventional metallic wire at high rates of shingle of environmental conditions when all other variables of the physical situation are fixed. A generalized attack on the problem of the responses of homogeneous and two-material marinated cylinders to sinusoidal environmental temperature changes has accordingly been made. The results are applicable to situations in which small heat-transfer coefficient changes occur in the absence or presence of environmental temperature changes.
