An international team of researchers, lead by a team at the University of Michigan, have discovered that Coulomb Interactions dissipate heat better than expected. “The scientists demonstrated that the electrostatic interactions between electrically charged particles — known as Coulomb interactions — in different layers of multi-layered graphene offers a key mechanism for … [Read more...]
Solution to Heat Transfer in Phase Change Materials Unveiled
Dr. Patrick Shamberger, assistant professor at Texas A&M University, has found an “analytical solution to heat transfer in PCMs (Phase Change Materials) used in thermal energy storage and has identified the relative role of thermo-physical properties of different materials,” according to Phys.org. Shamberger is one of the lead researchers studying high-energy storage … [Read more...]
Thermal Invisibility Cloak Improves Heat Distribution in Electronics
A team of researchers from the Nanyang Technological University (NTU) in Singapore has developed a thermal invisibility cloak that would improve heat distribution in electronic devices by redirecting incoming heat. The cloaks are capable of guiding heat around a hidden object, thus resulting in complete thermal invisibility. “Based on carefully engineered metamaterials – … [Read more...]
Comparison of HPC and Telecom Data Center Cooling Methods by Operating and Capital Expense Extended Article
Dr. Alexander Yatskov Thermal Form & Function Inc. Introduction Current high-performance computing (HPC) and Telecom trends have shown that the number of transistors per chip has continued to grow in recent years, and data center cabinets have already surpassed 30 kW per cabinet (or 40.4 kW/m2) [1]. It is not an unreasonable assumption to expect that, in accordance … [Read more...]
The Holy Books of Heat Transfer: Facts or Fairy Tales?
By: Clemens J.M. Lasance; Guest Editor The answer to the question stated in the title is both! It all depends on whether or not your situation is truly similar to the situation described in the book (physically congruent, fluid mechanically and thermally similar). Very few heat transfer books provide detailed dimensions and flow conditions for the experimentally observed … [Read more...]
