WebConvection is the collective motion of particles in a fluid and actually encompasses both diffusion and advection. Advection is the motion of particles along the bulk flow Diffusion is the net movement of particles from high concentration to low concentration We typically describe the above two using the partial differential equations: WebThis is called the convective or advective rate of change of Q. Example - the material acceleration, following a fluid particle - The material acceleration can be derived as follows: Note that dt/dt = 1 by definition, and since a fluid particle is being followed, dx/dt = u, i.e. the x-component of the velocity of the fluid particle. buy scar 17
