Characteristics of Pool Boiling Heat Transfer of Stabilized Colloidal Single walled Carbon Nano Tube (SW-CNT) and Multi walled Carbon Nano Tube (MW-CNT

ABSTRACT
Heat transfer and Critical heat flux (CHF) in pool boiling of single-walled and multi-walled CNT nanofluids were investigated using horizontal surface. Homogeneous and stable nanofluids have been produced by suspending well dispersible single-walled carbon nanotubes (S-CNTs) and multi-walled carbon nanotubes (M-CNTs) into water base fluid. S-CNTs nanofluids (0.0001, 0.001, and 0.01 vol.%) and M-CNTs nanofluids (0.0001, 0.001 vol.%) were prepared for experiments. From zeta potential results our CNTs nano-fluids has a good stability, it was constant for more than one month. The experimental data obtained show that there were a significant enhancement of CHF using nano-fluids compare to water. Our findings indicate that have collective influence on the CHF enhancement of CNT nanofluids.
