Re: newbie looking for help

yes my problem was only to calculate the heat and the temperature. By the way there was a bad mistake in the math model... the prof did it... now i have a new mathematical model to work on... i hope that now is fine.... i'm doing this thesis with the prof of electrical machines and energy conversion...

Re: newbie looking for help

thank you but for the "solar part" my mathematical model is done. I calculatd the efficiency of an ipotetical motor using a graph edited by sunpower. In that graph there was the fraction of carnot efficiency (real efficiency/carnot efficiency) in funciont of the temperature ratio. Now i ha...

newbie looking for help

Hi all, I'm a student and i'm doing a work to graduate. I saw this forum and i think that its very intresting. My project consist in a stirling engine connected to a linear fresnel plant. To complete my mathematical model i need some datasheet of stirling engines. In particular i need the graphs of ...
