Document Summary
The brayton cycle is the ideal model of a gas-turbine with the same 4 processes as in the rankine cycle taking place in the ideal gas region. This is internal (in working substance) combustion vs. rankine external. Many new power plants using natural gas runs in this (open) cycle. Power density, as net work per size of the plant wnet/m or wnet/v, is high. From the process analysis qh = h3 h2; ql = h4 h1; wnet = wt wc = qh ql. Regenerator, configurations, intercooling, jet engine (cid:149) air standard refrigeration cycle (cid:149) otto cycle, gasoline engine (cid:149) diesel cycle (cid:149) stirling cycle (cid:149) combined cycles. 4 1 isobaric heat rejection, assumed heat exchanger. Everything is steady state with a single flow through 4 different components. 0 = s2 s3 + dq/t + 0. 0 = s3 s4 + (0/t) + 0. 0 = s4 s1 dq/t + 0 q = 0, s1= s2.
