Abstract: Computational fluid dynamics (CFD) can be used for modeling environment characteristics and for controlling instrumentation in sensitive environments, such as in an office building, datacenter, hospital, enclosed arena, airport, or other environment. In an example, power consumption characteristics from physical equipment assets in an environment can be used by a CFD circuit to improve accuracy of a CFD model. Information from a CFD model can be used to optimize efficiency of HVAC or other air-moving systems serving an environment. In an example, CFD analyses can be performed substantially in real-time when one or more inputs to a CFD model change, relative to a baseline value, by more than a specified threshold amount. An energy efficient and cost efficient response to a change in infrastructure of an environment can be identified based on a CFD model of the environment.

Abstract: A blower is formed with multiple sets of rotatable rings of blades coupled to each other. Multiple inlet rings are correspondingly coupled to the multiple sets of rotatable rings of blades. In one embodiment, the blades may be forward facing blades and include a volute to accomplish pressure recovery. In further embodiments, the blades are backward facing. Such backward facing blades are designed to provide a static pressure rise. In some embodiment, three or more rings of blades with corresponding inlet rings are utilized.
