摘要: The presence of a cold surface in non-isothermal pipe flows conveying submicron particles causes thermophoretic particulate deposition. In this study, an analytical method is developed to estimate deposition efficiency and its effect on overall heat transfer coefficient transition turbulent flow regimes. proposed solution has been validated against experiments conducted at Oak Ridge National Laboratory. Exhaust gas carrying soot was passed through pipes with constant wall temperature various designed boundary conditions correlate Prediction the reduction mass deposited compared experiments. results are reasonably good agreement
