Experimental Investigation On Natural Convection Heat Transfer Augmentation With Vibration Effect By Using Water-Al2o3 Nanofluid

[Full Text]






Natural convection, Heat transfer, Constant heat flux, Boundary theory layer, Vibration, Frequency.



Conventional fluids including water, engine oil, ethylene, ethylene glycol, and transformer oil have a lower thermal conductivity of fluid compared to strong. The nanofluid is used in different applications like commercial, heat exchange, motor car, and biomedical, etc. The nanoparticles and sodium dodecyl sulfate are mixed into a base fluid (water) for distinct volume fractions (0.05%, 0.1%, 0.15%, and 0.2%) and supply diverse heat inputs 30W, 40W, 50W, 60W. The Al2O3 nanoparticles are high thermal conductivity then Cuo. The SDS (sodium dodecyl sulfate) mixed with Al2O3 nanoparticles are suspension kingdom for a long time without settling at the lowest allocation of the square rectangular prismatic enclosure. The unbalanced motor positioned below the cylindrical surface then its floor is vibrated and its temperature increases. The dimmer stat used to various voltages and frequency 100Hz-190Hz. The fluid at constant in enters gadget then enhancement of heat transfer coefficient increase.
