Abstract. Leading edge erosion (LEE) is one of the most critical degradation mechanisms that occur with wind turbine blades (WTBs), generally starting from tip section blade. A detailed understanding LEE process and impact on aerodynamic performance due to damaged leading (LE) required select appropriate protection (LEP) system optimize blade maintenance. Providing accurate modeling tools there...

An overview of the parallel evolution computations and experiments in fluid dynamics context turbulent flows is given, viewed from an experimental side. It evident that can no longer be seen as only validations for forecasting “numerical wind tunnels” not yet valid. The growing evidence organized motions pushes both numerical approaches to develop new measurement technologies methods. Many tool...

Traditional fluid mechanics textbooks are generally written with problem sets comprised of closed, analytical solutions. However, it is recognized that complex flow fields are not easily represented in terms of a closed solution. A tool that allows the student to visualize complex flow phenomena in a virtual environment can significantly enhance the learning experience. Such a visualization too...

conventional compression ignition (ci) engines are known for their high thermal efficiency compared to spark ignited (si) engines. gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. using double injection strategy reduces the maximum heat release rate that leads to nox emission reduction. in this paper, a numerical study of a gasoline fuel...

This paper presents the study of fluid flow and heat transfer in a plain rectangular duct of a solar air heater by using Computational Fluid Dynamics (CFD). The effect of Reynolds number on heat transfer coefficient and friction factor was investigated. A commercial finite volume package ANSYS FLUENT 12.1 is used to analyze and visualize the nature of the flow across the duct of a solar air hea...
