On the Numerical Investigation of Natural-Convection Heat Sinks Across a Wide Range of Flow and Operating Conditions

Autor: Louis Dewilde, Syed Mughees Ali, Rajesh Nimmagadda, Tim Persoons

Publikováno v: Fluids, Vol 9, Iss 11, p 252 (2024)

Many designs for natural-convection heat sinks and semi-empirical correlations have been proposed in the recent years, but they are only valid in a limited range of Elenbaas numbers El and were mostly tested for laminar flows. To alleviate those limi

A Parametric Design Study of Natural-Convection-Cooled Heat Sinks

Autor: Oisín McCay, Rajesh Nimmagadda, Syed Mughees Ali, Tim Persoons

Publikováno v: Fluids, Vol 8, Iss 8, p 234 (2023)

Effective natural-convection-cooled heat sinks are vital to the future of electronics cooling due to their low energy demand in the absence of an external pumping agency in comparison to other cooling methods. The present numerical study was carried

Numerical investigation on regulation and suppression of heat and mass transfer by varying thermal and solutal buoyancy force

Autor: Ranjit J. Singh, Y S Kannan, Rajesh Nimmagadda, B Shukla

Publikováno v: Engineering Research Express. 5:015078

In this study, a three-dimensional numerical analysis is presented for regulation and suppression of heat and mass transfer by varying thermal and solutal buoyancy force with a rotating cylinder placed at the center of the cavity. The energy and conc

Thermal Management of Electronic Devices Using Gold and Carbon Nanofluids in a Lid-Driven Square Cavity Under the Effect of Variety of Magnetic Fields

Autor: Rony Reuven, Lazarus Godson Asirvatham, Somchai Wongwises, Rajesh Nimmagadda

Publikováno v: IEEE Transactions on Components, Packaging and Manufacturing Technology. 10:1868-1878

Heat is an inevitable by-product of every electronic device and thermal management is very much essential for them to improve reliability and to prevent premature failure. Liquid coolants are one of the best switching options to achieve higher coolin
