6 FAQs about [Slurry storage modulus]
Which slurry has a smaller storage modulus than loss modulus?
A slurry, in which particles are well dispersed and stabilized, usually has relatively smaller storage modulus compared with loss modulus and shows wider linear viscoelastic regime. However, in-whole slurry had 10 times larger storage modulus than loss modulus, and narrow linear viscoelastic regime being less than 0.1%.
What is the relationship between storage modulus & loss modulus in gap slurries?
For the GAP propellant slurries containing multimodal particles, the dependence of the storage modulus (G′) and loss modulus ( G ″) on the ratio of submicron-sized CL-20 to micron-sized CL-20 is complex. Moreover, the yield strain is barely altered, while the flow strain changes nonmonotonically.
What is the difference between AB slurry and storage modulus?
After the first mixing operation, the storage modulus is slightly larger than the AB slurry but smaller than the estimation, while the loss modulus increases roughly four times and is much larger than the estimation.
What is the difference between in-whole slurry and loss modulus?
However, in-whole slurry had 10 times larger storage modulus than loss modulus, and narrow linear viscoelastic regime being less than 0.1%. Additionally, loss modulus takes its maximum at the strain beyond the linear viscoelastic regime.
How are storage and loss moduli measured in viscoelastic slurry?
In the viscoelastic measurement, on the other hand, storage and loss moduli are measured as increasing the frequency logarithmically from 0.1 to 100 Hz at the maximum strain of 0.01%, being known as a frequency sweep test. When the maximum strain is sufficiently small, the internal structure of the slurry is maintained during this measurement.
How does frequency affect the modulus of a slurry?
The variation in the storage (G ') and loss (G ") modulus as a function of frequency at various temperatures is presented in Fig. 6 a. For all slurries tested when the frequency is increased, both moduli increase but in different manners, exhibiting frequency dependence.
