抄録

In-vivo and in-situ flow measurement technique for investigating flow behaviors of pressurized gas was presented. Magnetic resonance imaging (MRI) with highly pressurized gas was applied to examine characteristics of gaseous flow inside a Diesel Particulate Filter (DPF), which was installed in a non-magnetic high-pressure test vessel.<br> It is shown that signal intensity detected by MRI was enhanced using pressurized gas and that MRI techniques gives its feasibility to measure velocity distribution of pressurized methane gas. Results of velocity distirbution in the DPF cell revealed that fluid motion of gas inside the DPF cell was relatively uniform and that amount of fluid penetrating through the ceramic wall was not varied depending on the distance from the inlet.
