TL;DR: In this paper, an experimental investigation on heat transfer with porous media inserts during compression and expansion was conducted for a pressure ratio of 10 and 6, respectively, and the results showed that the surface area increase was the predominant cause for the improvement in performance.

TL;DR: In this article, a numerical simulation is performed to predict swirl cooling of an internal leading edge cooling passage model for a gas turbine blade, and the results indicate that the pressure loss and global area weighted average Nusselt number on the swirl chamber increases with increases of Reynolds number, and increases with decreases of the jet nozzle aspect ratio.

TL;DR: In this article, heat transfer measurements were made on a channel wall augmented with cylindrical pin fins, and velocity measurements were taken with a single-component laser Doppler anemometer in the presence of pin fins.

TL;DR: An engineering design for a 1-kW dual-cavity solar-driven reactor to capture carbon dioxide via the calcium oxide based two-step carbonation-calcination cycle is presented in this article.
Abstract: An engineering design for a 1-kW dual-cavity solar-driven reactor to capture carbon dioxide via the calcium oxide based two-step carbonation-calcination cycle is presented. In the low temperature carbonation step, gas containing up to 15% carbon dioxide flows through a gas manifold and plenum into an annular reaction zone filled with calcium oxide particles. The carbon dioxide reacts with the calcium oxide, forming calcium carbonate. Carbon dioxide-depleted gas flows out of the reactor through a second gas manifold. In the high temperature calcination step, concentrated solar radiation enters the beam-up oriented, windowless reactor and is absorbed by the diathermal cavity wall, which transfers heat via conduction to the calcium carbonate particles formed in the previous step. The calcium carbonate dissociates into calcium oxide and carbon dioxide. Additional carbon dioxide is used as a sweep gas to ensure high purity carbon dioxide at the outlet. Mechanical and thermal analyses are conducted to refine an initial reactor design and identify potential design shortcomings. Numerically predicted temperature profiles in the reactor are presented and the final reactor design is established.Copyright © 2015 by ASME

TL;DR: In this article, the authors simulated a deep-finned rectangular channel open on one end to a plenum and with a gap to allow flow over the tip of the agitator plate to strongly mix the nearwall flow, to thin the thermal boundary layer and to increase the convective heat transfer coefficient.
