“…To calculate the DRESOR values, an energy ray is tracked using the path-length method following the general procedure of the radiative energy absorption distribution method (READ). [133] The radiative intensity at any point with high directional resolution can be obtained based on the DRESOR values. The DRESOR method has been successfully used to calculate radiative heat transfer in onedimensional (1D), [134,135] two-dimensional (2D) [136] and threedimensional (3D) [137] systems with the particle media.…”

Keeping gas radiation is a major way of heat transfer in flames. It affects temperature distributions and hence causes energy transfer in the combustion gaseous as well as subsequent chemical reactions. Accurate and efficient modeling of radiative heat transfer in multi-dimensional combustion systems is challenging, due to the drastic and rapid change of the radiative properties of the reacting gases in the whole spectrum, and the extensive computational cost for solving the radiative transfer equation (RTE) in multi-dimensional space. Several gas radiation models and RTE solution methods have been proposed to treat non-gray radiation heat transfer in combustion systems. In this paper, we first review the development of spectral line databases, gas radiation models and RTE solution methods. Subsequently, the development of radiation model parameters for different gaseous species is discussed. Next, recent simulation investigations are reviewed for one-dimensional, twodimensional and three-dimensional systems involving these state-of-the-art radiation models. In addition, we also discuss machine learning approaches for establishing gas radiation models and solving RTEs in non-gray gas radiative problems, an alternative and flexible way to deal with the complex and dynamic systems. Hopefully, this review will provide an up-to-date knowledge about the numerical calculations of gas radiation heat transfers in combustion systems.

The microchannel heat sink (MCHS) is an efficient thermal management technology widely used in various fields, including electronic equipment, automobiles, and aerospace. In this paper, the recent advances in cross-sectional shape, coolant type, flow channel shape, flow pattern, and application scenarios of the MCHS are systematically reviewed. The liquid film thickness in circular microchannels is the smallest, followed by rectangle, trapezoid, and triangle sections. Conversely, the pressure drop experienced exhibits an inverse relationship with the liquid film thickness. Comparatively, the heat transfer performance of the liquid phase surpasses that of the gas phase, and the two-phase coolant consistently outperforms the single-phase coolant. The study also investigates the impact of flow direction and shape on heat transfer performance. It is found that the implementation of wavy, fractal, and cavity structures enhances heat transfer performance at the expense of increased fluid motion variability, resulting in a loss of pressure drop. Additionally, this paper discusses the occurrence of laminar and turbulent flow phenomena within MCHSs and summarizes their respective influences on heat dissipation performance. On the basis of the aforementioned findings, four key applications of MCHSs are emphasized, accompanied by recommendations for their present utilization and future development. Future research endeavors will concentrate on striking a balance between altering the shape and material characteristics of MCHSs to optimize heat transfer performance while developing novel theoretical models continuously.
