This article presents the results of numerical simulation that evaluates influence spray angle gasoline (С6Н6) in combustion chamber on temperature distribution and formation carbon dioxide concentration. The purpose this work is to study initial parameters process liquid fuel using based solution two-dimensional differential equations turbulent reacting flow. studies were carried out at 20-160...

We study the properties of t-t -V model of hard-core bosons on the triangular lattice that can be realized in optical lattices. By mapping to the spin-1 /2 XXZ model in a field, we determine the phase diagram of the t-V model where the supersolid characterized by the ordering pattern x ,x ,−2x “ferrimagnetic” or SS A is a ground state for chemical potential 3V. By turning on either temperature ...

INTRODUCTION Vertebral metastases are associated with significant pain, disability, and morbidity. Open surgery for fracture stabilization is often inappropriate in this population due to a poor risk-benefit profile, particularly if life expectancy is short. Percutaneous vertebroplasty and kyphoplasty are appealing adjunctive procedures in patients with malignancy for alleviation of intractable...

In this work, a strategy based on the grafting of vanadium molecular complex, [V(═O)(OtBu)3], (1), bearing tert-butoxide ligands, partially dehydroxylated silica, followed by thermal treatment has been used for preparation supported tripodal V oxo [(≡SiO)3V(═O)], active species, important chemical processes. The complex reacts with silica at 200 °C (SiO2–200) to lead bipodal [(≡SiO)2V(═O)(OtBu)...

Most flamelet models for turbulent combustion assume that a turbulent diffusion flame behaves locally as a steady, one-dimensional, laminar, strained flame. While this assumption works well in many practical applications, it fails to take into account finite rate kinetic effects that occur at low Damköhler numbers. It has been shown by Cook et al. (1997) that a steady laminar flamelet model ove...

We present methods and algorithms that allow the Vlasiator code to run global, three-dimensional hybrid-Vlasov simulations of Earth's entire magnetosphere. The key ingredients make Vlasov at magnetospheric scales possible are sparse velocity space implementation spatial adaptive mesh refinement. outline algorithmic improvement semi-Lagrangian solver for six-dimensional phase quantities, discuss...
