                         technology that has been undergoing in this institute towards its 
                         application in future space missions. An experimental program has 
                         been developed to execute performance tests in LHPs to check their 
                         operationability over the time. An alternative working fluid has 
                         been used during the development of this program, which is the 
                         high grade acetone, as this fluid represents less hazard and 
                         reduced costs of purification and transfer when compared to the 
                         ammonia. The performance test results have been used to validate a 
                         transient type mathematical model that was conceived to evaluate 
                         LHPs performance in space conditions, focusing in future 
                         applications of LHPs in satellites payloads, where the condensate 
                         film thickness in the radiator condenser tube is determined by the 
                         solution of the conjugate equations of energy, momentum and mass 
                         balance in the control volume. Evaporator and compensation chamber 
                         are both described by a few transient nodes with generalized key 
                         parameters. In the transport lines the fluid temperature, 
                         pressure, enthalpy and vapor quality are tracked, making the model 
                         tolerant to eventual condensation on inner wall surface in the 
                         vapor line or vapor migration into the liquid line. The model is 
                         closed by the loop overall mass balance. The results of this 
                         investigation are of great importance for future LHPs design.",
