Abstract: By experiment, the effect of length/diameter ratio, inlet configuration, and bend angle on the capillary flow coefficient was investigated and some methods for improving flow were presented. The difference in flow coefficient between single-pipe injector and multiple-pipe injector and the effect of firing test on the capillary flow coefficient were discussed in the paper
