Abstract:
This paper summarizes the results of a pilot experimental program intended to develop robust data for global airflow through cracked concrete, with comparisons against a traditionally used prediction method. Current models for predicting airflow through concrete based on Poiseuille flow poorly translate to large-scale specimens and real-world conditions without calibration. This paper presents a novel testing apparatus that will be used to identify key variables affecting flow rate and develop numerical prediction methods for industrial applications.
