# I am trying to design an axial turbine for my project

• AhmedAB
In summary, a chemical engineering student is working on designing a geothermal power plant and has been tasked with designing an n-pentane turbine. However, they are struggling with understanding the main components and finding a detailed n-pentane steam table. They are looking for guidance on how to design a simplified version of the turbine and are limited on time. They have already done some work on determining temperatures, pressures, and flow rates, and are now seeking help with designing the nozzle, rotor, and blades. Due to financial constraints, they are unable to hire someone to do the design for them.

TL;DR Summary: I have a problem designing an axial turbine, there is a lot I don't understand

hey, how are you all doing, I am a chemical engineering student working on designing a geothermal power plant, weirdly I have been told that I must design an n-pentane turbine for our Plant, it's so confusing there is a lot I don't understand and sadly I don't have enough time to read entire books, so I am asking if you can guide me to how to design a steam turbine main components and how to can my design match my turbine work output. also, where can I find an n-pentane steam table I couldn't find one that was detailed, thank you so much for reading, and forgive me a lot for asking too much .

Perhaps you can hire someone to do that for you ?
And then you could also hire someone to design your turbine ...

Bottom line: what are you prepared to do yourself ?

A full design is far beyond the scope of a student design project, so you have to simplify. Focus on the cold side temperature, hot side temperature, and the distance between them. Look at the relationship between heat exchanger sizes and temperature drops across the heat exchangers. Then flow losses vs pipe sizes for the distance between hot and cold sides.

Then add all that up to find the temperatures and pressures at the inlet and outlet of the turbine, and the flow rate through the turbine. Put everything into a flow diagram. If time remains, start refining the design of major components.

I fully agree with you a full design seems like a pain to do, what I am aiming for is a way less detailed design more specifically about the measurement of the nozzle, rotor, blades, etc, I don't want to go deep into design cause it will take a huge portion of my time as you said, also all that you said is thankfully ready or being working on at the moment, also forgive me I am new to this forum I am trying to understand it more, thank you for responding I really appreciate it.

I wish I could hire someone but unfortunately, I am not able to finically so I am compelled to do it myself, but of course, not a full design just a simplified version, Thank you for responding I really appreciate it, its my pleasure really
