- Opis:
- Several turbulence models have been urbanized in the past decades, and many of them have been used in predicting airflows and turbulence in enclosed environments. It is vital to approximate the generality and heftiness of the turbulence models for various indoor airflow scenarios in various sections. The present work developed the geometry of the mine model gallery using CATIA version V5R20. It carried out air flow simulation for different inlet velocities and studied the air flow velocity through the section by grid section method and traverse method. An artificial flow regulator was created to study the flow behaviour and calculated Reynolds’s no at bends and turns to characterize the air flow. In this model the turbulence has also been calculated and the zone of turbulence is being located using Ansys fluent. The model was validated by comparing the results of the readings of the actual mine model gallery and by means of mass flow rate at different sections to establish a CFD model for mine gallery and validation of the results of flow behaviour, viz. air velocity, pressure profile, and determination of zone of turbulence of mine model gallery developed using Ansys 18.2.
