Flow and heat transfer characteristics of NACA vortex generator with curved-divergent walls are numerically studied the corresponding enhancement mechanism is also analyzed by local streamlines, velocity vector diagram contour diagram. The variation vortices at different positions along flow direction illustrated. impacts width W height H on as well pressure loss investigated Re ranging from 36...

Heat transfer is a working area where different numerical results are obtained from materials, environments, independent observations made, data can be collected at bases based on the abundance of input. effects heat transfer. The air flow, temperature and pressure were discussed. Unlike previous studies, construction fin made aluminum choice NACA 4040 wing profile as shape was one major factor...

Much human energy needs are obtained from fossil fuels. This is decreasing day by day. So that the utilization of natural such as solar energy, water and wind being developed. Wind we can find, so it very easy to use using a turbine driving force. The vertical axis type easier apply in places where potential not too large. research was conducted means simulation Qblade v0.963 software comparing...

Direct numerical simulations (DNS) of flow over an NACA-0012 airfoil are performed at a low and a moderate Reynolds numbers of Rec=50*10 and 1*10. The angles of attack are 5 and 15 degrees at the low and the moderate Reynolds number cases respectively. The three-dimensional unsteady compressible Navier-Stokes equations are solved using higher order compact schemes. The flow field in the low Rey...
