Effect of parameter variation on the viscosity of ethanol gel propellants

This research investigated how the variation of temperature and shear rate affects the viscosity of ethanol gel propellants that use methyl cellulose as gellant and, in parts, use boron as energetic additive. Using a rotational viscometer in a cone-and-plate configuration, propellant viscosity data was recorded across a range of temperatures...

On the Influence of Fines on the Sedimentation Velocity in Hopper Dredgers

Clay particles, known for their adhesive properties, are commonly encountered in underwater soils. When producing large quantities of sand by means of dredging, fines are a byproduct and cause important viscosity changing effects altering the sand settling behavior. Much is already known in this field but knowledge lacks in the area where sand...

Rheological Properties of Cohesive Sediment Suspensions

In order to predict the stain and shear rate response of cohesive sediment suspensions to applied forces, their rheological properties have to be known. In this report the rheological properties of both China clay, an artificial mud, and Caland channel mud, a natural mud, are investigated. Four types of experiments are involved: equilibrium flow...
