TL;DR: In this article, the authors present the results of a numerical study on natural convection heat transfer in an inclined enclosure filled with a water-CuO nanofluid, where two opposite walls of the enclosure are insulated and the other two walls are kept at different temperatures.
Abstract: This article presents the results of a numerical study on natural convection heat transfer in an inclined enclosure filled with a water-CuO nanofluid. Two opposite walls of the enclosure are insulated and the other two walls are kept at different temperatures. The transport equations for a Newtonian fluid are solved numerically with a finite volume approach using the SIMPLE algorithm. The influence of pertinent parameters such as Rayleigh number, inclination angle, and solid volume fraction on the heat transfer characteristics of natural convection is studied. The results indicate that adding nanoparticles into pure water improves its heat transfer performance; however, there is an optimum solid volume fraction which maximises the heat transfer rate. The results also show that the inclination angle has a significant impact on the flow and temperature fields and the heat transfer performance at high Rayleigh numbers. In fact, the heat transfer rate is maximised at a specific inclination angle depending on ...

TL;DR: In this paper, the authors reveal the inherent relation between the filed synergy principle and the three existing mechanisms for enhancing single phase convective heat transfer, i.e., decreasing of thermal boundary layer, increasing of flow interruption and increasing of velocity gradient near a solid wall, all lead to the reduction of intersection angle between velocity and temperature gradient.

TL;DR: In this paper, a two-dimensional transient heat transfer model for different methods of heat dissipation is used to simulate the temperature distribution in lithium-ion batteries, and it is found that forced convection cooling can mitigate temperature rise in the battery.

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.

TL;DR: In this article, a heat exchanger is constructed by arranging partition walls between two plates to form a fluid channel and a fin parallel with the channel or inclined by a prescribed angle on each of the two plates insides the channel so that the plate or a member in contact with the plate is cooled or heated with the fluid flowing through the channel.
Abstract: A method of using a heat exchanger efficiently and uniformly to cool or heats portions to be controlled to a prescribed temperature, and then continuously carry out stable processing. The heat exchanger is constructed by arranging partition walls between two plates to form a fluid channel and a fin parallel with the channel or inclined by a prescribed angle on each of the two plates insides the channel so that the plate or a member in contact with the plate is cooled or heated with the fluid flowing through the channel.
