Validated dataset combining simulations and measurements for emission analysis of naturally ventilated dairy barns

Year: 2025

Type: data-paper

Abstract: Quantifying emissions from naturally ventilated livestock buildings is challenging due to the large side wall openings. In addition, measurement campaigns are expensive and time consuming and are therefore limited to a few short measurement weeks during the year. However, emission factors or annual averages are extrapolated from these data sets. Simulations can complement this data set by extending it and thus broadening the basis for the extrapolation of emission factors or evaluation of the barn and management system. The dataset presented consists of solution data from computational fluid dynamics (CFD) simulations of naturally ventilated cattle barns and the corresponding simulation and geometry files. The simulations were validated using data sets from measurement campaigns in three naturally ventilated cattle barns in Germany. Together with weather data from the German Weather Service (DWD), weather situations that occurred outside the measurement weeks could be investigated. With the presented data set further investigations are possible. Together with the measured data, simulation techniques, data aggregation and the development of new numerical modelling approaches can be investigated in detail.
