Visualisation of Cfd Results in a Virtual Reality Environment

This paper describes our experiences with Virtual Reality visualisation of CFD results in an immersive environment. The data for visualisation were simulation results of airflow and temperature distribution in livestock buildings. Four different configurations of ventilation system were studied. Low momentum air supply was studied with air supply near the floor and through the ceiling respectively. High momentum air supply was studied in configurations with a slot inlet as well as a number of individual inlets. The three-dimensional airflow has been visualised in panorama and a six-sided CAVE. The flow was visualised by interactively controlled planes of velocity vectors and air temperature as well as streamlines and moving particles.
