Analysis of the supersonic flow of gas in the differentially pumped chamber EREM
Matloch, Roman ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
This work describes briefly electron microscopy issue and physical model of fluid flow. Then presented diploma thesis will be describing analysis and evaluation of the impact of supersonic flow on the pressure and density in the path of the primary electron beam in the differential pumping chamber. For analysis, evaluation and examination of the issue will be used CAD and CAE (Computer Aided Engineering) programs. At the same time it will be developed a methodology of calculation applicable to supersonic flow in the low pressure system at ANSYS CFX.
Evaluation of Gas Flow at the Proposed Shapes of Scintillation Detector Aperture Sieves
Matloch, Roman ; Špinka, Jiří (referee) ; Maxa, Jiří (advisor)
This work describes briefly electron microscopy issue and physical model of fluid flow. Then the simplified three-dimensional model of scintillation detector will be created in SolidWorks system for 3D cubical models. The gas flow behind the screening in this 3D model will be analyzed and compared by method of finite cube method in SolidWorks Flow Simulation system. This screening will be analyzed in several variants: the screening with 0.6 mm opening and the screening with net-like openings. The results of analyses will be compared according to the requirements. The appropriate shapes from the analyzed parts will be practically measured.
