The sloshing liquid during draining is equivalent to a set of mechanical model with variable parameters.
The purpose of this paper is to investigate the stress-dependent behaviour of clay during drained and undrained shearing by means of a micromechanical approach.
Using the proposed model, forces and torques acted on a Cassini shaped tank by the inside liquid during draining are investigated undergoing several typical motions.
The evidence includes erosion and deformation of glaciolacustrine sediment that we interpret happened during draining of the lake, desiccation cracks that formed during exposure of the lake bottom, and fluvial sand deposited as the lake began to refill.
The objective of these activities was aimed at the investigation of the thermal-hydraulic behavior of the full-scale divertor cassette both under steady state condition and during draining and drying operational transient.
First, our specialized sensor system is presented, and then the results obtained with the system model are compared to the results of actual experiments using the system to monitor the evolution of the medium during draining.
In the frame of the activities related to ITER divertor R&D, ENEA CR Brasimone was in charge by EFDA European Fusion Development Agreementto to investigate the thermal-hydraulic behaviour of the full-scale divertor plasma facing components, i.e. the outer vertical target, the inner vertical target and the dome-liner, both in steady state and during draining and drying transient.
The triaxial test results on very loose Ottawa sand indicated that sand behavior was affected by the size of the specimen during isotropic compression as well as during drained and undrained shear.
An overflow line (5) enables gas, originally in the empty tubes, to be transferred to the tank during fill cycles and for the same volume of gas to be transferred back to the phototube array during draining cycles to prevent suction from damaging the semi-rigid PET tubes.
Specimens were sheared following isotropic consolidation up to an axial strain of 30%% at an axial strain rate of 5%%/h (corresponding to 0.032, 0.042, and 0.058 mm/min for the 38 mm, 50 mm, and 70 mm specimens, respectively) to ensure full pore pressure equalization during undrained shearing and complete excess pore pressure dissipation during drained shear.
