sir/madam,
I finished BE in aeronautical Engg, and i want to go for MTech/MS in CFD.
My research Interest is hypersonics, shoch wave dynamics and propuslion. i want to choose my thesis related to hypersonics flow and heat transfer, but if i am going for Phd can i continue my research in propulsion area? is there any proplem with changing from aerodynamics to propulsion? because some of my freinds told me as getting admission in phd is depending on my master level research, thats why i am asking can i change the fields or is it difficult. please help me to take a good decision.

Thaking you
