Cryogenic pipe flow simulation for liquid nitrogen

Cryogenics is dealing with very low temperatures of less than 120 K. Applications of cryogenic can be found in variety of fields such as physics, chemistry, biology, medicine, engineering and industry. Cryogenic pipe flow is very different compared to normal fluid pipe flow in terms of evaluation an...

description	Cryogenics is dealing with very low temperatures of less than 120 K. Applications of cryogenic can be found in variety of fields such as physics, chemistry, biology, medicine, engineering and industry. Cryogenic pipe flow is very different compared to normal fluid pipe flow in terms of evaluation and analysis in terms of fluid state change caused by heat leak in cryogenics during transportation in transfer line. The present study is on liquid nitrogen pipe flow simulation in order to understand the flow characteristic and temperature distribution in the pipe flow. Computational fluid dynamics (CFD) software has been employed for the present study. The 3-dimensional liquid nitrogen pipe flow simulation has been conducted using ANSYS FLUENT to obtain the flow characteristic and temperature distribution. The turbulent liquid nitrogen pipe flow has been simulated and the flow velocity and the temperature distribution have been obtained.
