Description

Drying grains for safe storage is essential in agriculture. Traditionally, this technique was based on methods such as sun drying, which is slow and uneven. Computational fluid dynamics (CFD) simulation provides a valuable tool for increasing grain drying efficiency. Engineers can simulate the complicated interplay between airflow and individual grains by combining CFD with the Discrete Element Method (DEM). This enables them to model moisture transfer, temperature distribution, and grain movement inside the dryer. CFD-DEM simulations can help speed up, improve efficiency, and reduce the cost of grain drying processes.

Due to the importance of the drying process, it has tried to simulate drying of grains using ANSYS Fluent and MATLAB software considering DDPM and DEM approach.

DDPM-DEM CFD Simulation of Drying of Grains

 

Simulation Process

The simple rectangular domain is designed using Design Modeler software. A structured grid is also performed.

There are several crucial points about simulating the drying of grains. Firstly, the volume fraction of the grains is high. So, it needs to be considered as a Dense Discrete Phase Model (DDPM), plus considering the interaction between the grains (DEM). Secondly, the drying system is filled in the initial step, and the File DPM injection method is employed with respect to the grains array and, avoiding probable interaction between them. A code is written for this aim using MATLAB software. Last but not the least, the humid must be evaporated during the drying process, which is taken into account in the present simulation. This is where water vapour Species are defined using Species Transport model.

 

Post-processing

We conducted a simulation using DDPM-DEM modules to study the drying process of grains. Our focus was on visualizing the changes in the volume percentage of water vapor as time progressed. The animation effectively portrays the complex dynamics of the drying process. Our findings reveal a steady decrease in the amount of water vapor present in the grain bed. A thorough comprehension of this subject is crucial for optimizing industrial drying processes, improving product quality, and reducing energy use.

The animation extracted from the transient (unsteady) CFD simulation is shown below:
