The absorbed hydrogen...

... LNG instead of fuel oil as ship fuel is one of the best ways to solve the world's resource shortage and environmental problems today. LNG needs to be vaporized and pressurized, and then transported to the ship cabin area by gas transmission pipe. In the process of transmission, the pipe will leak...

...) simulation including a response surface-based optimization using the simulation software Ansys Fluent has been carried out to evaluate the most suitable operating conditions. Finally, this paper outlines a way to verify and validate the functionality of a helix pipe heat exchanger for cryogenic hydrogen...

..., bubbles generated at low pressure are sucked into the pump steel pipe with the water. Due to pressure differences, the bubbles implode, generating shockwave that impact the blades, causing pump vibration and mechanical damage, thus reducing the pump's lifespan. If excessive bubbles are drawn...
