Assessment of the Impact of Stagnation Temperatures in Receiver Prototypes of C-PVT Collectors [PDF]
Energies, 2019 Concentrating Photovoltaic Thermal (C-PVT) solar collectors produce both thermal and electric power from the same area while concentrating sunlight. This paper studies a C-PVT design where strings of series-connected solar cells are encapsulated with ...

Temperature-dependent microbial dynamics in touchless sensor faucets during short-term stagnation
Environmental Science and EcotechnologyMicrobial contamination in building plumbing systems poses significant risks to public health at the point of use. Stagnation and warm temperatures are well-known drivers of microbial regrowth, but the effects of common short-term stagnation in touchless

Impact of Stagnation Temperature and Nozzle Configuration on Rarefied Jet Plume Interactions [PDF]
Journal of Spacecraft and Rockets, 2022 The canting axis of thrusters on space platforms, which likely operate in a vacuum environment with a high degree of flow rarefaction, is significant in order to create the desired torque for manoeuvring, maintaining orbit, eliminating perturbation forces, docking, etc.

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification
Yuanzineng kexue jishu, 2022 When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.
