Let's see if I can assist:
Inboard engine strake
For the non-aero types, the need for the strake is due in large part to the disruption of airflow over the wing caused by the engines themselves, particularly as the AOA increases. The strake creates a vortex that adds energy to the airflow and helps delay airflow separation over the wing.
