Selecting optimal parallel microchannel configurations for active hot spot mitigation of multicore microprocessors in real time
Lakshmi Sirisha Maganti, Purbarun Dhar, T Sundararajan +1
Design of effective micro cooling systems to address the challenges of ever increasing heat flux from microdevices requires deep examination of real time problems and has been tack…
Bridging thermal and electrical transport in dielectric nanostructure based polar colloids
Purbarun Dhar, Arvind Pattamatta, Sarit K. Das
Heat and charge transport characteristics of nanocolloids have been bridged from fundamental analysis. The relationship between the two transport phenomena in dielectric nanostruct…
Percolation network dynamicity and sheet dynamics governed viscous behavior of poly-dispersed Graphene nano-sheet suspensions
Purbarun Dhar, Mohammad Hasan Dad Ansari, Soujit Sengupta +4
The viscosity of Graphene nano-sheet suspensions (GNS)and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced…
Thermally smart characteristics of nanofluids in parallel microchannel systems to mitigate hot spots in MEMS
Lakshmi Sirisha Maganti, Purbarun Dhar, T Sundararajan +1
Mitigation of hot spots in MEMS employing in situ microchannel systems requires a comprehensive picture of the maldistribution of the working fluid and uniformity of cooling within…
