... The complicate solution of replacing the gases with oxygen and then having the oxygen diminished by the reaction was solved again by this author (Bar-Meir 1995a). Even the minimum size of the vacuum consideration was investigated (Bar-Meir, Eckert, and Goldstein 1999) and the problem should be considered solved with the exception of the location and the number vents and gates. Another major source of entrapment is the shot sleeve where hundreds of teams have tried to solve in vain to solve the problem. ...

... THE FLOW of a mixture of a vapor and non-condensible gases, such as air and water vapor, through a porous medium, and the accompanying phase change (condensation) in the vapor phase and the multiphase transport processes involved have received considerable attention through problems related to different applications, such as phase change in building insulation materials [1][2][3], heat pipe technology [4], and others [5]. The condensing flow of a single vapor phase through a porous medium, on the other hand, has received relatively little attention [6]. ...

... Heat transfer is an essential topic in the field of engineering and plays a critical role in a vast range of applications, from designing efficient heat exchangers to optimizing energy consumption in various industrial processes. The study of heat transfer involves the analysis of the physical mechanisms that govern the transfer of thermal energy between different systems and environments, such as conduction, convection, and radiation [12]. ...

... Comparisons of these two cooling configurations on the SS revealed a better film cooling performance of the double row due to an improved film coverage and delay jet separation. Goldstein et al. [7] investigated film cooling on convex and concave curved surfaces for double row injection. ...

... The first analytical model for mass transfer in a compressible mainstream was introduced by Shapiro [19]. This topic has since been extensively discussed in classical compressible flow textbooks [20,21] and further elaborated in various publications [22][23][24][25]. Building upon these foundational works, the following section presents an analytical model for mass transfer in one-dimensional compressible flow. ...

... Many authors have investigated the typical endwall cooling technique of film cooling with discrete holes inside the passage, focusing on the effect of cooling hole geometry, flow parameters, and arrangement on the cooling effectiveness. For improving the endwall cooling effectiveness level, Jabbari et al. [2] and Friedrichs et al. [3] modified the arrangements of film holes to cover the entire endwall with the same level of coolant flowrate. Satta and Tanda [4] investigated the distribution of film cooling effectiveness of two discrete-hole arrangements in a turbine cascade endwall, and the re-design configuration was enabled to achieve better coverage of coolant. ...

... This application of Taylor Series expansion to finitely spaced nodes in space was later called Taylor Series formulation. In the 1980's, the representation of physical systems by use of control volumes became popular for modelling heat transfer systems [4,5]. This approach required the application of conservation of energy to every individual control volume. ...

... Two types of failures in a multiprocessor system are of interest, processor failures and link failures. Most of the previous research in designing optimal fault-tolerant topologies was concentrated on the cases that only processor failures were allowed [1, 2, 4, 6], or the cases that only link failures were allowed [3,5,7,8,[11][12][13][14][15]. In this paper, we discuss the case of a combination of processor failures and link failures for token rings. ...

... Many other researchers have focused on the glazing factor in solar box cookers as a means of performance enhancement (Mirdha et al., 2008, Eckert et al., 1996, Deubener et al., 2009, Akhtar et al., 1999. Common glazing material used in the construction of box-type solar cookers include glass, fibreglass, and acrylics. ...
