Hi Im developing a tool to generate a openFoam wind tunnel case of wind turbine, I already have the blade geometry constructed as the pictures show.

My example blade


I'm really new CFD and parametric meshing, I found some articles where mention a C topology to mesh the airfoil, also found a software (bladedesigner) that mention a topology named O10H, but none of these has a reference about how to implement this topologys and if are more topologys, or what are the best uses cases for each one.
can someone give me a reference at least to begin my search about how to make an efficient mesh for my tool.

Bladedesigner Topology O10H



Diferent Kinds off C topology
