This program involves the development of electrically cured (integral resistance heating) high temperature adhesive films suitable for bonding titanium and stainless steel honeycomb sandwich structures. These adhesives are based on high temperature polymers of the polyimide type. Phase I of this project involved the selection of the best electrical heating elements to be used in Phases II and III. CCA-1 carbon fabric and WCJ graphite were selected. Evaluation parameters included ...
The wave equation including source terms that arise because of introduction of heat into a medium has been used as the starting point for a small-signal analysis of the Rijke phenomenon. The dependence of the onset of oscillation on means flow velocity through the tube has been Found for three different values of heater power. The results of the analysis compare favorably with experimental results when the cutoff occurs at ...
