Abstract

A 3D transient CFD model is established to characterize heat and mass transfer phenomena in a museum showcase with environmental air exchange in Chongqing China Three Gorges Museum. The model is able to give detailed information about air temperature and velocity distributions in the showcase at different time points during the periods investigated. In order to evaluate the model’s accuracy, experiments are performed in two typical days in summer and winter, while the temperature variation data is collected. The model is validated with the experimental data and shows satisfactory accuracy with average deviation within 0.1°C. A numerical method to calculate air exchange rate (AER) of museum showcases with environmental air exchange is proposed for as an application of this model. The method simulates the carbon dioxide tracer dilution process in the showcase, and the simulated tracer concentration curves are used to calculate the air exchange rate of the showcase successfully. Calculation results in both cases show that AERs increase with environmental temperature. This work proves CFD to be a powerful tool in the modelling of museum showcases.
