Research areas for Master's course involving CFD applications
 

I want to choose a topic for my Master's course. I am interested in CFD and also have a good theoretical understanding it.
Because of the wide scope of CFD applications, I am not able to choose a particular topic also I am not aware of the current or future booming CFD application research areas.
Please guide me in finding a topic where I can use ANSYS FLUENT as a CFD simulation tool to supplement my research.
