Abstract : This paper showcased the cooling effects of Aluminum oxide (AONF), Copper Oxide (CONF) Nanofluids and water (H2O)on polyethylene stretching sheets for good surface finish and aesthetic look. The AONF had superfine structure when compared to CONF. The cooling effect of the NFs on SS with inner diameter of 10 mm, initial Die Temperature (DT) of 212°C and stretching velocity of 1.42 m/s was determined by measuring the transient temperature TT for 50 minutes at 10 minutes interval The experimental results for the peak temperature and heat properties for AONF CONF and water were: 57.5 and 60.3 and 64. 5°C, 1.01kg m3 ⁄ , 0.601 poise, 1.93x10−4 mol/dm3 and 0.60 wm−1K −1 and 1kg m3 ⁄ , 0.95poise, 0.00 mol/dm3 and 0.6 wm−1K −1 , respectively. The values obtained indicate the efficient effect of optimum heat and heat transfer of Aluminum oxide (AONF) and Copper Oxide (CONF) Nanofluids and water(H2O) on the stretching sheets. The aluminum oxide and coper oxide nanoparticles base- fluids revealed improved cooling characteristics on the polyethylene stretching sheets with minimal defects in comparison with water. The stretching sheets cooled with aluminum nanofluid exhibited the best cooling characteristics.

Keywords : Functionality, Cooling Effect, Heat Properties, Nanofluid, Stretching Sheet.
