The dynamics of the expulsion of the last liquid monolayer of molecules confined between two surfaces (measured recently for the first time) has been analyzed by solving the two-dimensional Navier-Stokes equation combined with kinetic Monte Carlo simulations. Instabilities in the boundary line of the expelled film were observed. We show that the instabilities produce a rough boundary for all le...

Aluminium murni memiliki castability yang baik tetapi sifat mekaniknya tidak baik. Oleh karena itu, untuk meningkatkan mekaniknya, ditambahkan elemen paduan lain seperti magnesium, tembaga, mangan, silika dan beberapa. Penelitian ini dilakukan mengetahui pengaruh temperatur tekanan tuang terhadap nilai kekerasan material pengecoran logam. Bahan menggunakan aluminium-tembaga (Al-6,7%Cu). Metode ...

in this paper, unsteady two phase simulation of nanofluid flow and heat transfer between moving parallel plates, in presence of the magnetic field is studied. the significant effects of thermophoresis and brownian motion have been contained in the model of nanofluid flow. the three governing equations are solved simultaneously via galerkin method. comparison with other works indicates that this...
