A grid (mesh) defines a tessellated collection of small volumes that cover the 3D volume of space that is to be simulated using CFD. The governing equations are integrated (discretized) over these volumes and solved iteratively until they those equations are satisfied. Out of the process comes predicted values of temperature, pressure, velocity etc. at each of those grid cells. … [Read more...]
Saving Energy with Every Byte: An Concerted Effort for Efficient Thermal Management of Data Centers
By Yogesh Fulpagare and Atul Bhargav Energy Systems Research Laboratory, Indian Institute of Technology Gandhinagar, India With the advancement of technology, the access to information has become rapid as well as ubiquitous. These mammoth resources which can be accessed through one click are stored and processed in data centers. These data centers are one of the largest and … [Read more...]
Energy Efficient, Waterborne Data Center
Recently, Nautilus Data Technologies, based in Pleasanton, Calif., has constructed a waterborne data center. “The production data center is under construction on a 230-foot long barge that will have 30,000 square feet of white space on multiple floors with the ability to mix and match rack power up to 60 kilowatts per rack,” TechTarget.com reported. The data center pumps … [Read more...]
New Cost-effective Method for Producing Graphene
Recently, researchers at the University of Glasgow in Scotland have discovered how to produce large sheets of high-quality graphene in a way that is 100 times less expensive than previous methods. “The University of Glasgow team decided to see if they could make graphene with copper foils, which are already being cheaply made in bulk to create common household lithium-ion … [Read more...]
New Platform for Nanoscale Thermal Measurements
A CCNY team led by physics professors Carlos Meriles and Elisa Riedo recently reported on a platform for nanoscale thermal measurements based on magnetic resonance, and optical and atomic force microscopy. “Their paper, ‘Imaging thermal conductivity with nanoscale resolution using a scanning spin probe,’ is based on a simple notion: that a hot probe in contact with a thermally … [Read more...]
