Pool boiling heat transfer characteristics of Al2O3 -water nanofluids is studied experimentally using a NiCr test wire of 36 standard wire guage diameter. The experimental work mainly concentrated on (1) change of critical heat flux with different volume concentrations of nanofluid and (2) flow visualization of pool boiling using a fixed concentration of nanofluid at different heat flux values....

Downward/opposed flame spread over laboratory wire samples under varied gravity conditions were investigated in the range from 0 G to 1 G. Reduced experiments are conducted by parabolic flights of an airplane. Limiting oxygen concentrations (LOCs) and rates (Vf) obtained as a function level, with concentration, forced flow velocity, characteristics such insulation thickness core material experi...

High-temperature erosion is a detrimental phenomenon in industries where particle flow exists, which the search for new materials and mixes to increase lifespan of mechanical components exposed crucial. The present work studied resistance two coatings at 25 °C (RT) 900 sandblast-type rig. were fabricated with cermet-type powders: (C1) commercial Cr3C2-NiCr (C2) mixed laboratory-conditioned powd...

The aim of this study was to assess the effect of different plasma arc welding parameters on the flexural strength of titanium alloy beams (Ti-6Al-4V). Forty Ti-6Al-4V and 10 NiCr alloy beam specimens (40 mm long and 3.18 mm diameter) were prepared and divided into 5 groups (n=10). The titanium alloy beams for the control group were not sectioned or subjected to welding. Groups PL10, PL12, and ...
