    Abstract: Spoilers are widely used on aircrafts as lateral control devices. Despite their wide usage, very little numerical and theoretical information exist. Numerical simulation of the full unsteady, compressible Euler’s equations over the NACA 23012 airfoil with spoiler is performed using a hybrid Least-Squares finite element/finite difference method coup...

    Abstract: Dr. Tao`s viscosity theory is a university theory can be applied to a lot of liquid suspensions with the discrepancy in permittivity or permeability between the suspended contents and the base liquid. Diesel is a mixture and can be considered as one of these liquid suspensions. We ever got pretty good test results with diesel by the electric field ... Show More
