| Abstract: | The relationship between the apparent viscosity/shear rate and the related experiment parameters was investigated.This experiment research focused on a special gelled propellant.The test results show the relationship between the apparent viscosity and shear rate could be obtained in large-scale parameter range.The results also indicate that the apparent viscosity decreases sharply as the shear rate increase.When the shear rate adds to 104 order of magnitude,the apparent viscosity does not change. |
