(I am new to this forum so please do forgive me if I am posting at a wrong place.) Hello, I am a final year student of BS Mechanical Engineering and method of characteristics is not a part of our curriculum. In-fact I heard of it first time after finally picking my FYP. My final year project is to design analyze and manufacture a CD Nozzle which would achieve Mach 3. I was told by my supervisor that I would have to build the profile of the nozzle using method of characteristics because he wants the profile to be generalized so that every time the inlet condition changes, the profile changes automatically. My supervisor who himself is only a doctorate has never studied MOC himself so he can not help me. I want to know what it is and how could I start practicing it. Moreover what are the pre-requisites to start learning it. Any help would highly be appreciated. Kind regards.
