The use of probability density function (PDF) methods for turbulent combustion simulations is very attractive because arbitrary finite-rate chemistry can be exactly taken into account. PDF methods are well developed for non-premixed turbulent combustion. However, many real flames involve a variety of mixing regimes (non-premixed, partially-premixed and premixed turbulent combustion), and the de...

AIMS/INTRODUCTION The primary aim of this systematic review was to provide an overview of the efficacy and safety of premixed insulin analogs in Asians, specifically East Asians, with type 2 diabetes. MATERIAL AND METHODS The MEDLINE, Embase, Cochrane Library and ClinicalTrials.gov databases were searched from 1 January 1995 to 26 November 2015. Randomized controlled trials involving East Asi...

NOx emissions in n-heptane/air partially premixed flames (PPFs) in a counter-flow configuration have been investigated. The flame is computed using a detailed mechanism that combines the Held’s mechanism for n-heptane and the Li and Williams’ mechanism for NOx. The combined mechanism contains 54 species and 327 reactions. Based on a detailed analysis, dominant mechanisms responsible for NOx for...

Micro burner is the fundamental element of a micro energy power system. The performance, output power, and efficiency system are directly involved by combustion stability, efficiency, temperature distribution exterior wall. Owing to small space resident short time premixed fuel/air, fuel difficult burn completely, resulting in poor burning flame stability. Therefore, study technology focus curr...

The objective of this work was to investigate the influence of preferential diffusion on flame structure and propagation of lean-premixed hydrogen-carbon monoxide syngas-air flame at elevated pressure using direct numerical simulation (DNS) and detailed chemistry. The physical problem investigated is lean-premixed H2/CO outwardly propagating turbulent spherical flame at constant pressure of 4ba...

BACKGROUND Lidocaine has been used widely to prevent propofol injection pain. Various methods of administration exist, such as lidocaine premixed with propofol or lidocaine pretreatment using a tourniquet, but it is unclear which method of lidocaine administration is more effective for the prevention of injection pain of propofol LCT/MCT. The purpose of this study was to compare pretreatment of...

OBJECTIVE Premixed insulin is a commonly prescribed formulation for the outpatient management of patients with type 2 diabetes. The safety and efficacy of premixed insulin formulations in the hospital setting is not known. RESEARCH DESIGN AND METHODS In a prospective, open-label trial, we randomized general medicine and surgery patients to receive a basal-bolus regimen with glargine once dail...

The present work numerically investigates the effect of a cavity implemented in premixed methane/air micro-combustor on enhancing its thermal performances and thermodynamic efficiencies for micro-thermophotovoltaic applications. 3D time-domain numerical model is first validated by comparing predictions with experimental data available literature. Then it applied to examine effects dimensionless...

Detailed numerical simulations of premixed and non-premixed C2H4/air flames were conducted, using six available kinetic mechanisms. The results help assess differences between these mechanisms and are of interest to proposed hydrocarbon-fueled SCRAMJET concepts, in which C2H4 can be expected to be a major component of the thermally cracked fuel. For premixed flames, laminar flame speeds were ca...
