I am using Nasa CEA code for calculating Isp for different Ae/At
ratios with chamber pressure of 1000 psi. Problem is Isp should have a
peak at optimum expansion condition i.e. when Pexit= Patm but with
increasing Ae/At ratios Isp's are increasing although the Pexit<Patm.
Can anybody who has used the code help me ?
