Effect of ventilation air velocities on diesel particulate matter dispersion in underground coal mines

This paper presents a detailed account of computational fluid dynamics (CFD) simulations undertaken to investigate the influence of intake (ventilation) air velocities on the flow patterns of diesel particulate matter (DPM) generated by a man-riding vehicle operating in a straight rectangular cross section tunnel in an underground coal mine. The simulation results are validated against an earli...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

A Review on Recent Findings on Amino Acids Requirements in Poult-Studies

Amino acids (AA) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. Although, some table values are available on amino acids requirement, AA requirements may vary due to changes in dietary composition and breeding selection. Thus amino acids requirements have remained an ongoing research topic. ...
