The paper aims to present a numerical simulation for fluid-structure interaction (FSI) of a blood flow over the aortic valve. The finite element discretization is adopted both for fluid and solid domains. The monolithic scheme is used for the strong coupling of fluid and structure to satisfy kinematic and dynamic equilibrium conditions at the interface.

When the airship moves in the air, the tail-wings play a very important role in controlling and maintaining stability. The choice of the tail-wing layout determines the design, manufacture, construction and aerodynamic shape of each type of airship. On the tail-wings extra wings, brake wings are also put to help the flight process of safety.

This article aims to present a numerical analysis of blood flow in the aortic valve using fluid-structure interaction simulation. The finite element method is employed both for fluid and solid domains, and the monolithic scheme is used for the strong fluid-structure interaction coupling to solve well the two challenges: add-mass and large deformation problems.

A lift table is a very common device in industry. To lift goods or people, this device employs a scissors mechanism. There are numerous designs for the scissors mechanism. Each schema will produce a different set of output responses when given the same set of input parameters. As a result, determining the best scheme is critical when designing an optimal lift table.

Performing accurate numerical simulations of molten salt reactors is challenging, especially in case of fastspectrum designs, due to the unique physics phenomena characterizing these systems. The limitations of codes traditionally used in the nuclear community often require the development of novel high-fidelity multiphysics tools to advance the design of these innovative reactors.

The environmental sensitivity maps would be envisaged as an elaborated scheme exchanging knowledge among numerous stakeholders at decision-making and execution levels. Local knowledge, scientific knowledge and public knowledge are required to associate toward the development of environmental sensitivity maps, particularly the identification of shoreline types and its sensitivity; compiling biology, human-use resource information; ranking, prioritising sensitive sites and resources at risk.

In this work, we developed a numerical solver, integrated it into the OpenFOAM platform, for modeling electroconvective flow. The solver deals with the system of Poisson-Nernst-Planck-Navier-Stokes equations. The finite volume schemes functioned in OpenFOAM were used for discretisation of the Poisson-NernstPlanck equations.

This study attempts to develop a numerical scheme for 2-D transient analysis under unsaturated conditions. First, the unsaturated groundwater flow was described using the mass conservation law. Then, the Finite Difference Method and Backward Euler approximation were applied for space and time discretization, respectively.

In this paper, we develop the Mickens’ methodology to construct a dynamically consistent Non-Standard Finite Difference (NSFD) scheme for a recognized computer virus propagation model. It is proved that the constructed NSFD scheme correctly preserves essential mathematical features of the continuous-time model, which are positivity, boundedness and asymptotic stability.

The simplest case of a homogeneous, cylindrical aircraft fuselage impacting a rigid target is solved analytically by using conformal mapping. After developing a numerical scheme for the case of an elastic target, we find that a simple dimensionless number, the damage potential, gives an accurate prediction of the impact force.

The routing strategy among cluster heads in multi-hop wireless networks is still a big challenge because of its inefficiency in energy consumption aspects. Therefore, in this paper, we propose a novel method that combining an unequal clustering problem and a simple multi-hop routing to prolong network life. The numerical results show that the proposed solution is more effective than other models in recent studies

The simplest ideas of antiaromaticity refer to regular monocyclic systems and the eigenfunctions of the Hückel Hamiltonian for 4n π electrons in such systems. The antiaromaticity is expressed in the energy penalty for such idealized systems relative to the Hückel energy for 2n noninteracting π pairs. Observed systems seldom achieve the regular planar geometry assumed in this picture, owing to their ability to ease the antiaromaticity penalty by departures from the regular geometry and also by export of the 4n π electrons’ charge to substituents.
