Master Thesis Report Development of Salome 2D & 3D Meshing template and Grid Generator 6|Development of Salome 2D & 3D Mesh- ing template and Grid Generator In this chapter, the report will discuss about the development of SALOME based 2D and 3D meshing template. SALOME is an open-source meshing tool developed by EDF, a french based research and development company. SALOME is equipped primarily with python based geometry and meshing modules that can be run in both batch mode and in Graphic User Interface (GUI) mode. The main aim in developing these meshing template is to be able to generate mesh automatically for similar geometries with minimal effort. The secondary aim is the need for open-source tools that can be coupled with the in-house blade modeller After the meshes were generated in SALOME, it is necessary to convert them into SU2 based mesh before the simulation can be executed using the SU2 CFD solver. Therefore, a SALOME-SU2 grid generator was developed. The first section of this chapter will touch on the development of 2D meshing template. The second section of this report will compare the CFD results from SALOME and UMG 2 generated mesh. The third section of this chapter will look into the development of 3D meshing template. The fourth section of this report will compare the CFD results from SALOME and UMG 3 generated mesh. Lastly, the fifth section of this report will look into the development of a grid generator which extracts meshing information from SALOME and writes SU2 based mesh. 6.1 Development of 2D Meshing Template In order to develop a SALOME based meshing template that have similar features to UMG 2, it is necessary to investigate the specific requirements needed for the generation of a good quality 2D mesh. An illustration of the required features for a 2D mesh is shown in figure 6.1. Figure 6.1: Features of a good quality 2D mesh 63

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
