جریان ناپایدار و انتقال گرما از فیلم نازک نانو فلوئورس بر روی یک ورقه کشش با میدان مغناطیسی متغیر و اثر لغزش سرعت قدرت

This paper presents an analysis for the flow and heat transfer of power-law thin liquid film over a stretching sheet with magnetic field and velocity slip effects. With the assumption of the thermal conductivity is power-law-dependent on the velocity gradient. Three different types of nanoparticles, Al2O3, TiO2 and CuO are considered with ethylene vinyl acetate copolymer (EVA) used as a base fluid. The results show that CuO has more remarkable effect on enhancing heat transfer of EVA melt than TiO2 and Al2O3. Furthermore, increase in slip parameter shows an enhancement in the temperature and thinner film thickness. (127KB)
