Till recently, the application of the detailed combustion chemistry approach as a predictive tool for engine modeling has been a sort of a ”taboo” motivated by different reasons, but, mainly, by an exaggerated rigor to the chemistry/turbulence interaction modeling. The situation has drastically changed only recently, when STAR-CD and Reaction Design declared in the Newsletter of Compuatational ...

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...

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...

A new combustion model is developed and applied to simulate combustion in dual-fuel engines in which the premixed natural gas is ignited by the combustion flame initiated by a diesel spray. The model consists of a diesel auto-ignition model and a flame propagation model. A G-equation model previously developed to simulate SI engine combustion was incorporated with an auto-ignition model to simu...

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...

BackgroundThe ‘long shadow’ of childhood bullying can extend beyond immediate adverse mental health and educational outcomes well into adulthood, with associated long-term social care costs. Reducing is therefore a public priority. KiVa, school-based anti-bullying programme, effective in reducing schools Finland currently being tested the UK through large-scale Stand Together trial.
