We compute the influence of an applied magnetic field on the Casimir energy of a massive scalar field confined between two parallel infinite plates using Schwinger's method from source theory. The boundary conditions are those of a vanishing field through the plates. The obtained results show that a strong magnetic field inhibits the bosonic Casimir effect and that a weak magnetic field increas...

Cooling plates in battery packs of electric vehicles play critical roles passive thermal management systems to reduce risks catastrophic runaway. In this work, a series numerical simulations and experiments are carried out unveil the role cooling (both between cells bottom plate parallel cell stack) on behavior modules under nail penetrations. First, we investigated side runaway propagation mit...

Effects of the uniform transverse magnetic field on the transient free convective flows of a nanofluid with generalized thermal transport between two vertical parallel plates have been analyzed. The fluid temperature is described by a time-fractional differential equation with Caputo derivatives. Closed form of the temperature field is obtained by using the Laplace transform and fractional deri...

An experiment is presented which succeeds for the first time in stimulating the formation of coarse plates of bainite by the coalescence of identically oriented individual platelets. Transformation under the influence of a tensile stress dramatically promotes the formation of the coalesced bainite by increasing the probability of growing parallel platelets in close proximity. Whereas the coarse...

Deduce the velocity distribution of steady flow of an incompressible fluid of density ρ and viscosity η between two parallel, coaxial annular plates of inner radii r1, outer radii r2 and separation h when pressure difference ∆P is applied between the inner and outer radii. As an exact solution of the Navier-Stokes equation appears to be difficult, it suffices to give an approximate solution ass...

Two parallel semi-infinite plates are joined together at their common end, with vacuum in the infinitesimal gap between them and acoustic fluid outside. The configuration is an idealization of a realistic structural member such as the bow or keel of a ship where the structural elements are joined at an acute angle. The exact solution for acoustic diffraction from the parallel double plate junct...

Recent work by Jaffe and Scardicchio has expressed the optical approximation to the Casimir effect as a sum over geometric quantities. The first two authors have developed a technique which uses the complex geometry of the space of oriented affine lines in R to describe reflection of rays off a surface. This allows the quantities in the optical approximation to the Casimir effect to be calculat...

Explicit and compact expressions describing the reflection and the transmission of a Gaussian beam by anisotropic parallel plates are given. Multiple reflections inside the plate are taken into account as well as arbitrary optical axis orientation and angle of incidence.

A hard sphere system confined between two parallel hard plates is investigated theoretically. Using extensive Monte Carlo computer simulations, the phase diagram is calculated for the whole range of densities and plate separations ranging from one to two particle diameters. There occurs a strong first-order fluid freezing transition and both very weak and strong discontinuous phase transitions ...

In this paper, we study the stationary incompressible power law fluid flow in a thin porous medium. The media under consideration is bounded perforated 3D domain confined between two parallel plates, where distance plates very small. perforation consists an array solid cylinders, which connect perpendicular direction, distributed periodically with diameters of small size compared to period. For...
