Ventilation Design Handbook on Animal Research Facilities Using Static Microisolators 
• Temperature 
• Concentration of CO 2 
Using the experimental data to provide boundary conditions, various room and ventilation 
conditions were simulated by CFD. These included: 
• Supply type 
« Exhaust number and location 
• Supply flow rate 
• Use of change station and its location 
• Number cages on the racks 
In total, 100 variations were simulated and these are detailed in section 2. The results are 
presented in section 3. 
Over 18,000 super computer hours (CRAY equivalent) and 10,000 man-hours were needed to 
complete the CFD and experimental parts of this project. 
It should be noted that these reports use Systems International (S.I.) units, that is kilogram, meter, 
second, Pascal ( 1 Newton per square meter), watt ( 1 joule per second) and degrees Celsius, with 
approximate conversions to Imperial units displayed for reference only. One exception to this 
rule is the use of cfm (cubic feet per minute) which is in common use for flow rates.
