In this paper, we show velocity images for liquid flow in a cylindrical pipe at Reynolds numbers of up to 5000. Three orthogonal velocity components are acquired from a single excitation over a timescale of 60 ms thus obtaining an 'instantaneous' description of the fluid flow in steady laminar and chaotic turbulent flow. It is also shown how the technique, termed the gradient echo rapid velocity and acceleration imaging sequence (GERVAIS), can be used to acquire acceleration (convective… CONTINUE READING
