摘要

This study aims to investigate the sensitivity of bubble sample size during the saturated nucleate boiling of ethane. Experiments were conducted on a horizontal flat surface, under pressures of 0.15, 0.2, and 0.3 MPa with heat fluxes varying from 14.27 kW m(-2) to 81.22 kW m(-2). Mathematical tools like statistical analysis were used for the standardized study on boiling. Sequential analysis and random sampling were conducted to investigate the sensitivity of bubble sample size. The trend in which parameters changed with sample size was observed. The relative deviation (a) was within 10%, 5%, and 2% for sample sizes of 40, 95, and 215, respectively. The analytical results could provide reference to establish uniform standards in the boiling field. In addition, common statistical analysis was performed to examine the data distribution characteristics of bubble departure diameters. The Gauss function was evaluated as the best fitted probability distribution function. Data distribution changed with heat flux and pressure. The experimental results have a direct and substantial contribution to the boiling area. (C) 2018 Elsevier Ltd. All rights reserved.
