Measuring space radiation shielding effectiveness

EPJ Web of Conferences, 2017
Passive radiation shielding is one strategy to mitigate the problem of space radiation exposure. While space vehicles are constructed largely of aluminum, polyethylene has been demonstrated to have superior shielding characteristics for both galactic ...

Experimental study on the overall cooling effectiveness of nozzle guide vane under high temperature and high pressure

Case Studies in Thermal Engineering, 2022
This study presents the overall cooling effectiveness of a nozzle guide vane with impingement-effusion in the conditions of the high temperature and high pressure at the mass flow ratios from KG = 0.09 to KG = 0.14. The temperature ratios change from KT =

The novel application of Fourier thermal analysis in foundry technologies

, 2014
The process of casting in sand moulds is used for a large volume of castings manufactured in the world. Internal channels and complex geometries of these products are formed by the placement of cores within the mould cavity. Resin-bound sand mixtures are

Thermal and exergetic analysis of Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) [PDF]

, 2013
Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) has been proposed to solve the problem of poor heat transfer during heat exchange process, which is caused by unavoidable decrease of temperature differences. This paper conducts a theoretical
