摘要: In the present paper, characteristic atmospheric saturated pool boiling curve is qualitatively reproduced for water on a temperature-controlled long and thin copper strip using coupled map lattice (CML) method known in non-linear spatio-temporal chaos dynamics. The height 0.7mm, indicating that of thin-e lm type. work modie es basic theoretical model proposed by Shoji 1998 terms nucleation superheat distribution mixing. stirring action bubbles modelled increasing e uid thermal diffusivity an enhancement factor. It assumed governed (a) from cavities heated surface, (b) diffusion, (c) bubble rising motion associated convection, (d) phase change (e) Taylor instability. effectiveness factor approach clearly seen its capability reproducing well predicting critical heat ux (CHF) same order magnitude actual value.
