Hi ,<\/p>\n

I am doing my final year engineering project on the modelling of a shell and tube heat exchanger , I modelled the heat exchanger and I have meshed it in Ansys mesh. I have a few doubts to clear up as follows: <\/p>\n

I would like to improve my mesh quality i have applied sizing methods on edges , faces of tubes and shells. I have shown the final quality metrics but I want to further improve such as in the points i have shown.<\/p>\n

– the mesh i used is tetrahedrons with the element size currently set at 3mm : <\/p>\n

    \n
  1. I want to improve the mesh metrics further by reducing the maximum skewness value, a few elements are at 0.86 ( i have attached mesh metrics , skewness plot and the elements that have the high skewness )<\/li>\n
  2. Doubt about the interfaces, in the fluent interface i see src and trg in interfaces , when i unselect the tube walls disappear , I would like to know about this but the walls dont display ( should i make these src and trg interfaces coupled as my heat transfer is from the tube surface to the shell side) <\/li>\n
  3. I would like to know about if i need to apply inflation to the tubes . <\/li>\n<\/ol>\n

    Thanks in advance ,<\/p>\n
