Abstract : Further analysis of the heat transfer data presented in the Second Quarterly Progress Report showed that the correct form of the heat transfer correlating parameter should be based on the sensible heat capacity of the (vaporized) fuel. When this is done, the variation of the heat transfer coefficient with residence time is eliminated. The results obtained from a special 13 point test at constant relative residence time have shown that the cracking pattern of the decomposing fuel is apparently influenced only by residence time and not by system pressure. The effect of spraybar design on the plugging of a simulated fuel injector was further investigated and the results indicated that the plugging tendency of the fuel can be decreased by proper spraybar design. The effect of the fuel impurities tested to date has been negative. No effect has been found on the operation of the vapor phase heat exchange system or on the heat sink of the fuel. (Author)
