Abstract
Convective heat transfer coefficients (CHTC) play a critical role in assessing the thermal behaviour of concrete bridge structures. However, so far, these coefficients have been proposed for bridge girders without accounting for the specific section configurations and the orientation of the girder surfaces concerning wind direction. This paper presents the outcomes of a study employing computational fluid dynamics (CFD) analysis in conjunction with heat transfer simulations using Comsol Multiphysics to determine CHTC values for the outer surfaces of concrete river bridge box girders. The research considers not only wind speed and surface temperature but also takes into account the geometric parameters of the girder sections. Predictive models for CHTC are formulated based on the simulation results using mathematical regression. By employing CHTC calculated based on these predictive formulas, the temperature distribution in concrete bridge box girders is computed and subsequently compared with measured data, demonstrating a high level of agreement.References
