Hello gentlemen,<\/span><\/p>\n

I’m<\/span> new in <\/span>this<\/span> forum and <\/span>I’d<\/span> like to <\/span>discuss<\/span> with <\/span>you<\/span> on a <\/span>topic<\/span> <\/span>that<\/span> <\/span>I’m<\/span> working <\/span>through<\/span>. <\/span><\/p>\n

I <\/span>have<\/span> to simulate a <\/span>resin<\/span> <\/span>jig<\/span> <\/span>that<\/span> <\/span>it’s<\/span> put in a <\/span>oven<\/span> for 2 hours with a temperature <\/span>cicle<\/span> (maximum 80°C). <\/span><\/p>\n

I <\/span>want<\/span> to <\/span>find<\/span> the temperature of the <\/span>jig<\/span> <\/span>during<\/span> and <\/span>at<\/span> the end of <\/span>the <\/span>heating<\/span>. <\/span><\/p>\n

 <\/p>\n

I <\/span>created<\/span> <\/span>a <\/span>Transient<\/span> Thermal <\/span>simulation<\/span>,<\/span> I<\/span> <\/span>imported<\/span> the<\/span> <\/span>jig<\/span> <\/span>and<\/span> <\/span>a<\/span>n air cube (<\/span>1m3, I <\/span>removed<\/span> the volume of the <\/span>jig<\/span>); I set the <\/span>material<\/span>,<\/span> <\/span>resin<\/span> <\/span>and<\/span> <\/span>air, with <\/span>density<\/span>, <\/span>isotropic<\/span> <\/span>thermal<\/span> <\/span>conductivity<\/span> and <\/span>specific<\/span> <\/span>heat<\/span> <\/span>parameters<\/span>. <\/span><\/p>\n

 <\/p>\n

<\/p>\n

 <\/p>\n

I set the temperature like a <\/span>cicle<\/span> on the 6 <\/span>outer<\/span> <\/span>surfaces<\/span> of the air cube and I set the <\/span>conductivity<\/span> <\/span>between<\/span> the <\/span>jig<\/span> and the air. <\/span>Please<\/span> <\/span>think<\/span> <\/span>that<\/span> I <\/span>have<\/span> an industrial <\/span>oven<\/span> (like 16m3) <\/span>that<\/span> works with hot air. <\/span><\/p>\n

 <\/p>\n

I <\/span>solved<\/span> the system to <\/span>find<\/span> the temperature of the <\/span>jig<\/span>, <\/span>but<\/span> after 2 hours the <\/span>jig<\/span> <\/span>is<\/span> <\/span>at<\/span> 24°C. <\/span><\/p>\n

 <\/p>\n

Are <\/span>there<\/span> <\/span>any<\/span> <\/span>mistakes<\/span>? <\/span>Should<\/span> I <\/span>have<\/span> to <\/span>modify<\/span> <\/span>anythings<\/span>? <\/span><\/p>\n

 <\/p>\n

Let<\/span> <\/span>me<\/span> <\/span>know <\/span>if<\/span> I <\/span>was<\/span> clear. I <\/span>remain<\/span> <\/span>avaiable<\/span> for <\/span>any<\/span> <\/span>clarification<\/span>. <\/span><\/p>\n","protected":false},"template":"","class_list":["post-251194","topic","type-topic","status-closed","hentry","topic-tag-3DTransientThermal-1","topic-tag-air","topic-tag-ansys-transient-thermal-2","topic-tag-heatingtemperature-1"],"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\n\t\t\n\t\t\n\t\t
