grids between tip clearance

my model is a axial pump,and the tip clearance is very short to the whole radius. and i met a problem for grids.

when i make ogrids for blade,i don't know where to put the ogrids vertices between the shroud and blade tip. and some grids are always wrong with small angel ,such as 0-9 degree. how to avoid this situation?

thank you very much!

Re: grids between tip clearance
I dint get your question saying the axial pump having a shroud? In axial flow pumps the impeller blades are with the hub only. What is the clearence between impeller and casing.?
