Ejector Modeling and Examining of Possibility of Replacing Liquid Vacuum Pump in Vacuum Production Systems

Design and Performance Analysis of Double-Flux Supersonic Air Ejector

“…In order to examine the flow within an ejector system (one-dimensionally), several assumptions are implemented to choose the appropriate method ( [30], [31]). The system is divided into segments and the stations are assigned as seen in Figure 12.…”

Theoretical and experimental investigation of optimization conditions in the design of an ejector cooling system

“…Ejektör boğaz kesit alanının hesaplaması Denklem (23)'te verilmektedir [11], [46], [47]. Denklem (23)'te verilen ısı sığası veya adyabatik üs (Υ), / oranından elde edilmektedir.…”

Comprehensive Modeling of Vacuum Systems Using Process Simulation Software

“…However, when it came to the vacuum-based technological processes, the influence of the vacuum system was often overlooked, potentially compromising the accuracy of the modeling results. In reference [11], a specialized user module was incorporated into HYSYS to address this gap by computing steam ejector pumps, which are crucial in vacuum systems. Additionally, [12] emphasized that neglecting the intricacies of the technological process when modeling vacuum mixture condensation using such programs could introduce errors.…”

“…If the temperature of the refrigerant at the condenser inlet is 28 • C, and at the outlet is 38 • C, then the temperature t cannot be lower than 39 • C [5,6]. Meanwhile, the maximum temperature (t2) is approximately 50-60 • C since at higher temperatures, the condensation of the mixture would be insufficient [10,11]. Additionally, if the rear end head types are L or M (according to standards [14]), the allowable temperature difference between the wall and the jacket cannot exceed 40 • C.…”
