ABSTRACT
 
 Two macro-roughness patterns namely spiral grooving and diamond knurling were performed on an AISI/SAE 1045 cylindrical steel bar. Al2O3 + 13 wt.-% TiO2 powder was deposited by utilizing a multi-pass torch. Microstructure, microhardness wear resistance analyzed. The presence of both γ-Al2O3 α-Al2O3 throughout the coating promoted partially melted un-melted particles; howev...

In scramjet engines, ignition must take place within a residence time on the order of milliseconds. this study, secure conditions for specified n-octane pyrolysis fuel components used in autoignition or forced-ignition by plasma jet torch high-speed flow were numerically investigated. First, delay combustor and cavity flame-holder was estimated using chemical reaction analysis. Three (n-C8H18, ...

Gas metal arc welding (GMAW) is a highly efficient and fast process for fabricating high quality weld. High quality welds are fabricated by proper selection of consumable includes gas and filler metals. The optimum flow rate of gas will ensure the proper quality of weld. In this project, a fluid flow behavior of different flow rate is modeled and the change quality will be studied. KeywordsHydr...

INTRODUCTION The Study to Understand Mortality and Morbidity in COPD (SUMMIT) is a randomised controlled trial conducted in patients with COPD and comorbid cardiovascular disease, designed to assess the ‘impact of Fluticasone Furoate/Vilanterol combination (FF/VI) and its individual components on the survival of patients with moderate COPD and either a history of CVD or at increased risk for CV...
