A FORCED-CONVECTION AND NUCLEATE-BOILING HEAT-TRANSFER TEST APPARATUS

OSTI ID:4088203
BS>For most liquid propellants used in rocket engines, the ability to cool thrust-chamber walls locally is established by the upper limit of nucleate boiling. An experimental apparatus utilizing electrically heated tubes to obtain boiling heat-transfer characteristics of numerous propellants is described. The effects of deposition and electrically conducting fluids on heat-flux measurements, as well as precautions that must be considered when testing monopropellants, are discussed. Comparisons are made of variableproperty and constant-property equations for computing temperature difference across an electrically heated tube wall. (auth)
