TL;DR: In this article, the performance characteristics of subcritical organic Rankine cycle (ORC) based combined heat and power (CHP) system according to a variation of major operating parameters and to confirm the possibility of system performance improvement were investigated.

TL;DR: In this paper, the relationship between the shock structure of impinging jet flow and target wall heat transfer characteristics was investigated and the cooling performance of a supersonic nitrogen (N2) jet was investigated by measuring the impinged surface temperature, and the flow of the jet was visualized by schlieren imaging.

TL;DR: In this paper, the authors proposed a dry-ice assisted jet impingement cooling method for carbon dioxide (CO2) solid-gas two-phase jet and single-phase nitrogen (N2) jet.

TL;DR: In this paper, the authors examined the pressure drop characteristics of sub-cooled two-phase microchannel heat sinks and proposed a new model for conditions where subcooled flow boiling persists along the entire microchannel and the outlet fluid never reaches bulk saturation temperature.

TL;DR: In this article, the authors proposed an interlocking double-layer mini-channel heat sink that can realize counterflow in which the flow direction is opposite in the adjacent channel, and the heat transfer characteristics of the heat sink are analyzed by separating the change in the single channel heat transfer coefficient increased by the counterflow channel effect.
