1) Overview of the SW package ANSYS-Mechanical (environment philosophy, basic drawing tools, solving possibilities) 2) Transformer calculation: preparation of 3D model (including parameterization), setting of boundary conditions, adaptive and manual networking, selection and setting of solver. - Calculation of stationary temperature field (constant loss load, constant boundary conditions) - Calculation of non-stationary temperature field (variable load, variable boundary conditions), calculation of losses in iron. 3) Thermal calculation of the rotating machine - Geometric layout and mathematical slot replacement - Defining an air gap - Boundary conditions 4) CFX flow - fundamentals of flow, load of model, boundary conditions, types of tasks 5) CFX flow - heat transfer in the liquid, heat transfer at the interface, net effect, surface roughness. 6) Combined task - obtaining boundary conditions using CFX and possibility of their implementation in thermal model. 7) Combined Task - Continuation - Calculate the temperature field in ANSYS CFX. 8) 1D tasks of ANSYS simplorer, finite element method in time domain 9) 1D tasks of coupled model transfer, load transfer, results processing 10) 1D tasks of continuation of coupled model transfer, load transfer, result processing, parameterization 11) Individual work 12) Individual work 13) Presentation of individual work
