excuse me i wanna make fluent simulation about Greenhouse temperature and humidity<\/div>\n
 <\/div>\n
I tried to enter the air value with a temperature of 25 Celsius and 80% RH,<\/div>\n
but, because fluent doesn’t provide input for RH,<\/div>\n
so, I use species mixture template (water-vapor and air).<\/div>\n
the air  temperature is 25 Celsius and  teh RH is 80%,<\/div>\n
in that condition, the air has H2O mass fraction of 0.016 (psychometric table)<\/div>\n
 <\/div>\n
then I enter the value of H2O mass fraction at the inlet and outlet<\/div>\n
 <\/div>\n
 <\/div>\n
what I expect is the result of the RH contour at the end of the simulation is still the same 82%,<\/div>\n
but why do I get an RH that is less than 82% (only 10%)..<\/div>\n
 <\/div>\n
 <\/div>\n
is there a way so that I can get the RH of 82%??<\/div>\n
 <\/div>\n
 <\/div>\n
thank you<\/div>\n","protected":false},"template":"","class_list":["post-251807","topic","type-topic","status-closed","hentry","topic-tag-fluent","topic-tag-humidity","topic-tag-hvac"],"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
