...Nathan B. Crane Pyrometers are commonly used for high temperature measurement, but their accuracy is often limited by uncertainty in the surface emissivity. Radiation heating introduces additional errors due to the extra light reflected off the measured surface. While many types of specialized...

... . In the experiments, both flow visualization and temperature measurements are used. The effects of port location and deflector installation are examined. The experimental results are presented in a dimensionless form, as the normalized outlet temperature versus dimensionless time. Three-dimensional transient...

.... Simultaneous experimental and numerical investigations are performed. In the experiment, both flow visualization and temperature measurements are used. Three-dimensional transient numerical simulations are done using the FLUENT 6 software. Validation of the numerical model is achieved by comparison...

... temperature measurement solidification melting Energy production and consumption is the main driver of all urban and industrial activities. At present more than 80% of the world energy is provided by the combustion of fossil fuels, which includes oil, gas, and coal. The combustion of fossil fuels...

...Aaron P. Freid; Paul K. Johnson; Manuela Musella; Reto Mu¨ller; Julie E. Steinbrenner; Robert D. Palumbo We developed a method that enables one to correct solar blind pyrometer cavity temperature measurements for the system-sensor reflection error. The method is valid for measurements made...

... temperature reading. For the specified instrument design, the whole irradiated solar spot remains on the receiver for 5 minutes. The predicted and measured response time is about two minutes. Therefore, more than two minutes are left for the stable temperature measurement. Comparison between the measured...

... with discharge, only temperatures measured near the tube can be used as T ∞ . When the enclosure is isothermal or only slightly stratified, the reference temperature can be measured anywhere inside the enclosure except in the hot zone at the top or within the cold flow sinking from the tube...
