A versatile battery module platform houses either high‐energy NMC (155 Ah) or high‐power LTO (23 Ah) lithium‐ion cells for marine hybrid propulsion. Cell‐level failure tests guide the venting design, while a stainless‐steel–ablation hood withstands the up to 580 kW particle‐laden thermal‐runaway jet and aerogel gap fillers block propagation. Both fully

GAS actuated micro-jet pump for micro-fluidic systems
We present the results on the design, fabrication, and performance of a gas-actuated micro-jet pump for integrated micro-fluidic systems. Vacuum suction mode provided by the pump can effectively decrease the formation of air bubbles and overcome the ...

Multiscale simulation of non-isothermal microchannel gas flows [PDF]
This paper describes the development and application of an efficient hybrid continuum-molecular approach for simulating non-isothermal, low-speed, internal rarefied gas flows, and its application to flows in Knudsen compressors.

The acceleration of micro- and nano-particles in supersonic De-Laval-Type nozzle [PDF]
The particle velocity in cold gas dynamic spraying (CGDS) is one of the most important factors that can determine the properties of the bonding to the substrate. The acceleration of gas to particles is strongly dependent on the densities of particles and

Joint European Effort Towards Advanced Rocket Thrust Chamber Technology [PDF]
The achievements of the FSCD group during the last three years are described. For the case of nozzle flows in quiet ambience, new observations of the plume behaviour for truncated ideal nozzles are ...

A cold strontium Rydberg gas [PDF]
Cold gases of Rydberg atoms are an ideal system in which to study the novel effects of strong interatomic interactions. This thesis describes the design and construction of the world's first experiment to study Rydberg states in a cold gas of an alkaline

The Altitude Adaptive Dual Bell Nozzle [PDF]
The dual bell nozzle has been found out to be one of the most promising concepts for alti-tude adaption of the nozzle jet. The wall contour inflection linking the base nozzle with the ex-tension provides two stable operating modes, circumventing the area

Study Gas Flow Heating In Micro-Nozzle Through Walls Instead Of Preheating
Previously, Preheating has been established in micro-nozzles to increase the specific impulse of thrusters and increase thrust level. However, heating may cause higher viscous losses in micro-nozzles working at low Reynolds numbers. In this work, heating
