39. Performance and Modeling of Heat Flux Sensors in Different Environments
Series: OTHER
Published: 1/1/1999
Authors: David G Holmberg, C A. Womeldorf
Abstract: Heat flux measurement is not simple; care is required in selecting a suitable sensor for a given application. Surface substrate properties and the convective and radiative environment determine the choice of sensors. Mounting of the sensor, especiall ...
