Background

Mr. Saber obtained his BS, 1988 in Mechanical Power Engineering, with general grade "Excellent with Honor Degree" from Mansoura University, Egypt. He obtained his MS, 1992 in Mechanical Power Engineering from the same University. The title of his thesis was "Second Law Analysis in Heat Exchangers". He presented the concept of entropy generation as a convenient method for estimating and maximizing the performance of the heat exchangers.

Mr. Saber obtained his Ph.D. in Nuclear Engineering from the University of New Mexico. The title of his dissertation is "Operation Envelope and Performance Analyses of Closed Two - Phase Thermosyphons". He has developed a model for predicting the flooding limit in closed two-phase thermosyphons. Mr. Saber has also developed a model for determining the operation envelopes of closed Two-phase thermosyphons. This model can be used as an effective tool for designing thermosyphons for different operating conditions and type of applications. Mr. Saber has contributed to the developed of heat transfer correlations for small, uniformly heated liquid pools, in different pool heat transfer regimes (natural convection, nucleate boiling and combined convection regimes), and for liquid film in different film heat transfer regimes (laminar convection, nucleate boiling and combined convection regimes) in the evaporator of closed, two-phase thermosyphons.

Mr. Saber is investigating and modeling the effects of thermocapillary and evaporation and the mechanisms affecting stability of thin liquid film and which could cause film breakup. He is also applying the results of this investigation to the modeling of the dryout limit in smooth thermosyphons and in assessing the performance of grooved thermosyphons.

Mr. Saber has developed "A Multi-species Countercurrent Diffusion Model" for etching depleted Uranium oxide (UO2) in NF3, RF glow discharge plasma. The results of this model helped to explain the effect of the plasma pressure and the absorbed power on the etch rate of UO2.

Mr. Saber has contributed for developing "A Model for Predicting the Performance of Segmented Thermoelectric Unicouple". This model can be used as an effective tool for designing segmented thermoelectric unicouple for power systems of space applications.
