The pressures were varied from 0.4 MPa to 1.1 MPa. The non-boiling heat transfer characteristic agrees with that predicted by Dittus-Boelter correlation. The critical heat fluxes are higher for higher flow rates and lower pressures. Effect of Weber number on the CHF was clarified and a CHF correlation that can describe the experimental data is derived based on our correlation for a pipe., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: PA1520045000}, title = {Forced convection heat transfer from a wire inserted into a vertically-mounted pipe to liquid hydrogen flowing upward}, volume = {568}, year = {2014} }
