Pharmaceutical & Medical Research Applications
Examples of how CFD may be used to evaluate air quality, contamination control and ventilation performance of procedure rooms, animal holding rooms and labs.
Small Animal Holding Room with an Air Capture and Containment System
This room is designed to house small animals such as mice or rats. The animals are kept in groups of three to five per cage, in racks containing 30 shoebox cages. A slice is cut through the room to demonstrate temperature distribution and another to show velocity vectors. This design makes use of natural thermals from the racks in addition to the momentum from the supplies to drive contaminants toward the ceiling where they are efficiently extracted.
Small Animal Holding Room with a Sliding Curtain
This room is designed to house small animals such as mice or rats. The animals are kept in groups of three to five per cage, in racks located behind thin plastic curtains with many 40mm holes. This design allows fresh air to enter from the supply at the center of the room, pass through the curtain holes, ventilate the racks and be extracted from the room without further re-entrainment back to the central aisle. Experimental comparison reveals an extraordinary correlation for both temperatures and velocities.
Large Transgenic Mouse Holding Room
This room is designed to house small animals such as mice or rats. The animals are kept in groups of three to five per cage, in 40 stationary, 7 foot high racks. Streaklines are shown flowing from radial diffusers on the ceiling to high ceiling returns between each row of racks.
Small Animal Surgery Suite
This suite is designed for surgical procedures on small animals. The main operating room can accommodate five surgeons simultaneously using Isoflurane anesthesia gas. Each surgical station is fitted with a back draft table, overhead radial diffusers and heated table tops. Both iso-surfaces of Isoflurane (2 ppm) and particle tracks are shown in this figure.
