Hi guys, i’m Italo and I’m a student of energy engineering!<\/p>\n

I’m facing a challenger of my termodynamics professor to create a case of a tank with a vent to prevent over pressure where there is methane under pressure in two-phase state. There’s heat flowing from enviroment to the interior which causes phase change (boil off). My question is:<\/p>\n

1 – How can I construct a vent-like object what acts like a overpressure valve?<\/p>\n

Although I have made some research about the theme, nothing useful was found. I try some papers, youtube tutorials, even the officials tutorials of Ansys.  Actually, that issue could be a new tutorial, isn’t. “Simulation of boil off methane with mass flow rate measurement in a vent (or valve)”<\/p>\n

2 – If is impossible build such object, how can I measure the mass that is being convert in gas in respect of time in Ansys? That is a typical mass and heat transfer problem.<\/p>\n","protected":false},"template":"","class_list":["post-294389","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
