It has been shown that by increasing the film coefficient "h" by means of forced convection the heat transfer rate of a finned pin can be considerably improved. For an average flow rate of air over the extended surfaces, ...

<p>The concept of using heat flux measurements to provide the input for a feedforward temperature control loop is investigated. The feedforward loop is added to proportional and integral feedback control to increase the ...

The concept, design, fabrication, and calibration of a new type of layered heat flux gage is described. Using thin-film microfabrication techniques the gage design is able to combine many of the desireable characteristics ...

<p>Infrared sensor satellites, which consist of cryogenic infrared sensor detectors, electrical instrumentation, and data acquisition systems, are used to monitor the conditions of the Earth's upper atmosphere in order to ...

<p>Infrared sensor satellites are used to monitor the conditions in the earth's upper atmosphere. In these systems, the electronic links connecting the cryogenically cooled infrared detectors to the significantly warmer ...

The goal of this thesis is to develop a set of standards for use in calibrating heat flux gages at elevated temperatures in a radiant heat transfer environment by comparing several "trial" standards. Ideally, the same ...

A basic study on the convective flame-wall heat transfer in diesel engines was performed with a fundamental experiment and simplified theoretical models. Based on the concept of flame tubes, a combustor was designed and ...
