The purpose of under floor plenum in a typical raised floor data center is to route the supply of cold air to perforated tiles in the cold aisles, and hence, to the racks. However, the presence of under floor chiller piping and various wiring may have an adverse effect on flow rates if not placed based on physical considerations; the pressure drop caused by chiller piping and under floor blockages...
The ability to control mixing of reagents in MEMS systems is crucial for many biological and chemical analysis applications. However mixing in these microfluidic devices is a challenge because the flows are laminar corresponding to very low Reynolds number. In this paper, mixing of two aqueous reagents is studied in a "tau" shaped microchannel by means of computational fluid dynamics (CFD)...
Data center facilities house large number of computer servers that dissipate high power. With rapid increase in the heat flux of such systems, their thermal management has become a challenge that needs to be addressed. In this paper effect of isolating cold aisle on rack inlet temperature is studied computationally. Two raised floor data center configurations with alternating hot and cold aisle arrangement...
In a typical raised floor data center, under floor plenum supplies cold air to the computer room via perforated floor tiles. Thermal management of any data center primarily depends on air flow rates through the tiles. These tile flow rates are a function of several factors that govern the flow pattern under the raised floor. CFD analyses of an ideal raised floor can often be misleading as they may...
