TL;DR: In this paper, a simple theoretical analysis that indicated more energy and lower MCHS wall temperature could be obtained under the assumption that heat transfer could be enhanced by the presence of nanoparticles was carried out.
367 citations
TL;DR: In this article, the cooling capacity, junction temperature, coefficient of performance, and required heat sink thermal resistance at the TEC hot side were computed for thermoelectric cooler applications in the electronic cooling.
287 citations
TL;DR: In this article, the performance of silicon microchannel heat sink using nanofluids as coolants was analyzed based on theoretical models and experimental correlations, and it was found that the performances were greatly improved for these two specific geometries when nanoffluids were used as the coolants.
270 citations
TL;DR: In this paper, the inlet/outlet arrangement effects on the fluid flow and heat transfer inside the heat sinks are numerically investigated, and it is suggested that better heat sink performance can be achieved when the coolant is supplied and collected vertically.
210 citations
TL;DR: In this article, the velocity and temperature distributions in the microchannel heat sink were obtained by modeling the MCHS as a porous media, which was then used to evaluate the thermal resistance.

TL;DR: A review of the current state-of-the-art experimental and computational techniques for turbulent dispersed multiphase flows, their strengths and limitations, and opportunities for the future can be found in this paper.
Abstract: Turbulent dispersed multiphase flows are common in many engineering and environmental applications. The stochastic nature of both the carrier-phase turbulence and the dispersed-phase distribution makes the problem of turbulent dispersed multiphase flow far more complex than its single-phase counterpart. In this article we first review the current state-of-the-art experimental and computational techniques for turbulent dispersed multiphase flows, their strengths and limitations, and opportunities for the future. The review then focuses on three important aspects of turbulent dispersed multiphase flows: the preferential concentration of particles, droplets, and bubbles; the effect of turbulence on the coupling between the dispersed and carrier phases; and modulation of carrier-phase turbulence due to the presence of particles and bubbles.

TL;DR: In this paper, the authors present an exhaustive review of the literature in this area and suggest a direction for future developments, including heat transfer, material science, physics, chemical engineering and synthetic chemistry.
Abstract: Suspended nanoparticles in conventional fluids, called nanofluids, have been the subject of intensive study worldwide since pioneering researchers recently discovered the anomalous thermal behavior of these fluids. The enhanced thermal conductivity of these fluids with small-particle concentration was surprising and could not be explained by existing theories. Micrometer-sized particle-fluid suspensions exhibit no such dramatic enhancement. This difference has led to studies of other modes of heat transfer and efforts to develop a comprehensive theory. This article presents an exhaustive review of these studies and suggests a direction for future developments. The review and suggestions could be useful because the literature in this area is spread over a wide range of disciplines, including heat transfer, material science, physics, chemical engineering and synthetic chemistry.
