System and method for predicting perforated tile airflow in a data center

摘要

Systems and methods provide determinations of airflow from a raised floor plenum. In one aspect, a computer-implemented method is provided for predicting airflow from a plurality of openings in a plenum. The method includes (A) receiving input data from a storage device, the input data including data related to the plenum (B) determining an average air pressure in the plenum, (C) determining an airflow value for each of the openings based on the average air pressure, (D) dividing the plenum into a plurality of grid cells, (E) using a first iterative method, determine a value for airflow velocity for each of the grid cells, (F) determining an air pressure value at each of the openings based on the airflow velocity, (G) using a second iterative method, determine a new airflow value for each one of the plurality of openings based on the air pressure value at the one of the openings, (H) determining whether a difference between the new airflow values and previous airflow values is greater than a threshold, and (I) repeating acts (E) through (H) until the difference is not greater than the threshold, and then storing the new airflow value for each one of the plurality of openings as a final airflow value.
