Abstract
This report, Volume 10 of the 11-volume report on the master design simulator (MDS), describes the ventilation subsystem. This subsystem has the capabilities to handle (1) branches in parallel or series, (2) fans in parallel or series, (3) multiple fans, (4) methane, compressed air, or other injections into the system, (5) leakages and fixed quantities, and (6) calculations of absolute pressure at nodes. The program uses the kirchhoff junction and mesh laws, and the hardy cross iterative technique to converge to the desired accuracy in solving for the head quantity. A case study is included in the report illustrating the use of the model. The appendices comprise a user's manual and a program listing.
