Shaped-tube sheet for heat evaporator by finite element analysis with APDL and optimization

Because of lacking design standard of shaped-tube sheet for evaporator,the thickness of the tube-sheet is thicker in engineering design.For the sake of getting reasonable thickness,the steady-state temperature field,mechanical field and thermal stress field of the series of the evaporator tube-sheets were processed by finite element analysis.So it can be seen that the influence of the temperature on tube-sheet is obvious,engineering design of the tube-sheet was conservative and the tube sheet can be optimized.All the results have laid the foundation for the tube-sheet design method.
