vijesh joshi Guest Posts: n/a	Hello friends, I am a new to the Fluid dynamics subject. PLZ help me in understanding the terms below. convection, diffusion, dispertion and advection. I am learning CFX software. In one of my problems I got a shock wave at the front of the nose of the body. Can you plz explain why it gets birth?. (up till now I know that it is due to pressure difference)Also that, whether temperature, pressure and density are more at the tip of the nose when the blunt cone body flies at supersonic or hypersonic speeds?
