Abstract

To investigate the airflow resistance through packed wheat bed, static pressure was measured at various moisture contents (14.5-29.8w. b.) and superficial velocities (0.227-0.975m/s). It was recognized that there was a moisture content dependency in the airflow resistance. In this study, using the Ergun's equation, an attempt has been done for the calculation of airflow resistance as the function of moisture content. As a result, it was shown that the calculated values are fitted well with the measured values.
