multidimensional modelling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission and rate of heat rele...

Laser-driven electron recollision is at the heart of the rapidly growing field of attosecond science. The recollision wavepacket is qualitatively described within the strong-field approximation, which commonly assumes tunnelling ionization and plane-wave propagation of the liberated electron in the continuum. However, with increasing experimental sophistication, refinements to this simple model...

In the present work, we propose a novel model coupling phase-field, dislocation density based plasticity and damage. The governing equations are constructed on evolutions of mobile immobile dislocations. Mechanisms including multiplication, annihilation, mobile–immobile transfer due to interactions block interfaces incorporated in model. Especially, “swallow-gap” problem surrounding coarsened s...

• A novel meshless approach for phase-field modelling of dendritic growth. Reduction discretisation-induced anisotropy by the scattered nodes. Increase in computational efficiency a space-time adaptive approach. numerical is developed an accurate and computationally efficient solidification. The adaptivity based on dynamic quadtree domain decomposition. decomposes into rectangular sub-domains d...

To study the dynamical mechanism which generates Parkinsonian resting tremor, we apply coupling directionality analysis to local field potentials (LFP) and accelerometer signals recorded in an ensemble of 48 tremor epochs in four Parkinsonian patients with depth electrodes implanted in the ventro-intermediate nucleus of the thalamus (VIM) or the subthalmic nucleus (STN). Apart from the traditio...

abstract purpose-the purpose of this paper is to review a sample of the literature relating to interpretive structural modelling (ism) and its deployment for modelling purposes in the area of supply chain management (scm). design/methodology/approach- the literature is examined from the three perspectives. first, concept of ism and examines ism as modelling technique. second, use of ism by the ...

the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...
