Journal ArticleDOI
Efficiency of a Miller engine
TL;DR: In this paper, the relation between thermal efficiency, compression and expansion ratios for an ideal naturally-aspirated (air-standard) Miller cycle have been derived using finite-time thermodynamics.
Journal ArticleDOI
Effect of drag reducing polymers on oil-water flow in a horizontal pipe
TL;DR: In this paper, the effect of water soluble polymer solution (PDRA) concentration and molecular weight on flow patterns and pressure drops are presented in a horizontal 0.0254 m pipe and the results showed a significant reduction in pressure gradient due to PDRA especially at high mixture velocity.
Journal ArticleDOI
Thermodynamic modeling of spark-ignition engine: Effect of temperature dependent specific heats ☆
TL;DR: In this article, a theoretical model of the air-standard SI engine with temperature dependent specific heat has been implemented and compared to that which uses constant temperature specific heat, in most cases there were significant variations between the results obtained by using temperature-dependent specific heat with those obtained at constant specific heat.
Journal ArticleDOI
Efficiency of miller engine at maximum power density
TL;DR: In this paper, the effect of maximizing power density on the performance of the cycle efficiency is discussed. And the results obtained from this work can be helpful in the thermodynamic modeling and in evaluation of Miller engines over Atkinson and Joule-Brayton engines.
Journal ArticleDOI
Effect of drag-reducing polymers on annular gas–liquid flow in a horizontal pipe
TL;DR: In this paper, the authors used an annular configuration of a 0.0953 m pipe for air and water flow and showed that the injection of polymer solution produced drag reduction of about 48% with concentrations of only 10-15 ppm in the liquid.
