Reheat in Brayton cycle - gas turbine

- In a gas turbine, reheating is a process in which the hot gases coming out of the combustion chamber expands in two turbines i.e. high pressure and low pressure turbine. The hot gases firstly expands in a high pressure turbine then passes through a heat exchanger and then expands in the low pressure turbine. The reheating is carried out in order to enhance the regeneration effectiveness in heat exchanger and then expands in the low pressure turbine. However, only reheat leads to loss of thermal efficiency of Brayton cycle. In this lecture following points can be learnt
1) what is reheating in gas turbine
2) Why reheat alone reduces the thermal efficiency of gas turbine
3) In which case reheat will improve the thermal efficiency of cycle
I am fan of Indian Teachers,
What is the concept behind taking one as HPT and another as LPT turbine
A lot better explanation than others! Thanks.
Awesome video with clear concept
Thank you very much sir 🙏
Very nice explanation 👍👌😀
Why go to 3' ? We should be going to the point just below 4 -> name if 4'. And then our area increases... ???
Nice Sir, I request to you please show P-V diagram also to understand easily ! Thanks sir.
Which turbine gives more work output 1) high pressure turbine or
2) low pressure turbine.
We cannot comment on work output only on behalf of pressure alone because compressor work also gets increased for a high-pressure turbine, but yes if regeneration is employed in a cycle it will increase the work output due to increase in exergy of the compressed air at the inlet of the combustion chamber. I hope the doubt is clear.
How cycle is completed when 4-1 process doesn't happen as it happens in closed cycle
entire atmosphere is taken as heat sink.
it is equivalent process
love you man
Nice video
Sir but the third turbine u showed is also a HP turbine know
No it's LPT
It's an open cycle ,why you joined 6-1?
that is equivalent heat loss if we take it as closed cycle,
