A detailed finite-difference approach is presented for the simulation of transient radial flow in multi-layer systems.
This layered, composite structure is thin relative to previously developed, multi-layer systems with a resistive layer/low dielectric layer/resistive layer/low-dielectric layer structure.
It allowed for the investigation and understanding of complex ageing mechanisms, often observed in multi-layer systems with a variation in the running conditions.
A numerical study on the elastic response of single- and multi-layer systems formed by alternating pentamode lattices and stiffening plates is presented.
Using our methodology, wrinking can be predicted and controlled in multi-layer systems, with applications ranging from stretchable electronics to biomimetic design.
The solution is compared to existing (semi) analytical models for the simulation of slug tests and pumping tests with constant discharge in single- and multi-layer systems.
Since it is applicable to multi-layer systems, its use is not limited to the simulation of traditional pumping and slug tests, but also includes advanced aquifer tests, such as multiple pumping tests or multi-level slug tests.
The present paper attempts to introduce a numerical approach for the contact behaviour of multi-layer systems and establish an initial link between the contact stresses and performance of the surface engineered gears.
The water molecules absorbed at the interface are crucial to the durability of multi-layer systems and a general mechanism governing the failure modes of such systems is found.
Coupling between pressurized gas sorption and tensile behavior was studied in several semi-crystalline polymers: a Polyethylene (PE), a Polyamide 11 (Pand) and multi-layer systems based on these two materials were tested in tension into hydrogen (30 bars) and nitrogen (30 bars) atmosphere and compared to experiments into atmospheric air.
Zirconia (ZrO2) titania (TiO2) and alumina (Al2O3) thin films were deposited on a graphite substrate both in mono- and in multi-layer systems, using the metal organic chemical vapor deposition technique, to test their practical qualities as protective coatings against oxidation at high temperatures.
