Abstract : The studies described clarify the effects of some of the limitations imposed by the laws of thermal similitude, and determine the thermal modeling laws for a heat pipe. In Volume II the thermal modeling laws for a heat pipe were derived and experimentally verified. It was observed that prototype thermal behavior could be predicted, from model data, to within 10 F over the temperature range tested (140 to 330 F). Heat pipe failure due to capillary failure was also predictable to within plus or minus 10%. A flexible heat pipe was also designed and experimentally tested. Performance was not degraded under conditions of bending. (Author)
