Experiment and Numerical Simulation on Rush-Bundle Drying

Abstract

Rush-bundle is usually dried by a heated air dryer after immersing in mud water. A study on a drying process of the rush-bundle has not been performed sufficiently. Especially, a theoretical simulation has never been made so far. A simulation model is presented on the basis of the characteristics of the single rush drying process and the theoretical simulation on the rush-bundle drying process is made. An experimental study is also performed in order to compare between the experimental data and theoretical calculation. As a result, we obtained the following conclusions; 1) It is found that the present simulation model is useful to describe the drying process of a rush-bundle, because the results of the experiment and simulation are in close agreement. 2) The heat transfer from drying air to rushes is hardly affected by a mud sticking to the surface of rushes.
