The deposition density distributions of droplets in pipes are measured and are compared with the calculated results in order to verify the calculation model of droplet movements used in the calculation program of fuel behavior in an automobile intake manifold. The experimental apparatus consist of a rectangular straight pipe (one side 0.03m) and a mock intake manifold (diameter 0.03m) in which air flows. Mock fuel liquid (water) colored with ink is injected in a pulse from a fuel injector. This is recieved by a paper on the opposite side of the injector, and by processing the concentration of color by an image scanner, the deposition density distributions are measured. In all deposition density distributions of droplets, the calculated shift of deposition density distribution due to the air flow agrees with the measured values within ±10%.
