HE Thermal &Mechanical Design 1

[ikarga]

Rescheduled to Vessel department in order to learn and do quite new job form me - heat exchanger thermal & mechanical design. Please advice me how and from where to start? Any free examples?

Thank you

Depends upon you - what you want to achieve.

The GPSA Databook (if you have one or access to) has sufficient data to guide you in heat exchanger design/analysis.

Of course, there are your co-workers/fellow engineers (the crusty specialists) that can teach you as well.

I cannot remember the textbook name, but a good heat exchanger design textbook is helpful, but these are not free.

Good Luck!

Thank you pmover...
So far I want to learn to learn to do HE design, actualy to specialize this branch of vessel design. I am ready to work hard, also to do computer design, but have to learn the basis...

ikarga,

Good luck... We all want things that are free...

In what country are you located and where wil these heat exchangers be installed ?

Which international design standards will apply ? ASME ? ISO ? BS ?...?????

Will these be shell-and-tube or plate frame HXs or perhaps some other type ?

Do you have a mechanical engineering background ?

MJC,
I am mechanical engineer.
This is shell-and-tube exchanger. Will be installed in Lybia. The code is ASME...

ikarga,
Your endeavour is commanding;- that's the only way to learn and do a good job. Don't be afraid to make mistakes, I have learn most of my trade from my own mistakes.
However, the thermal design has to start with the understanding of the heat transfer principles, ie from the books. I don't want to recommend any particular one, because I don't know your financial resources and nothing is cheap. Start reading the free downloads from the web, just type in "heat transfer". There are many resources, read everything. Then start learning the principles of pressure vessel design. Buy an old copy of TEMA and read it three times until you can recite it backwards. Try to apply the ASME BPV code to the available designs and see how do you stack up to those rules. ASK MANY QUESTION ON THIS FORUM, specific question each time. Remember, only the smart one can learn from the smart and dumb one, only the dumb knows everything so he doesn't have to learn. I don't want to discourage you, but this trade takes hard work, sometimes decades to understand "why" is it so. I, for myself, I got today to understand now how little I know.
best of luck,
gr2vessels

Thank you gr2...
So far I am reading "STANDARDS OF TUBULAR EXCHANGERS MANUFACTURERS ASSOCIATION" Fifth Edition (1968 )
I am "workoholic", and totaly aware what is in front of me...Work, work...and work..

I concur with the recommendation to start with the TEMA and the 1968 version is a good one to use. When you have mastered the concepts therein you will be well along on your journey, but realize that it is only the beginning.

Also, if you always start with the adage that heat transfer is a function of Time, Temperature and Turbulence you will have a good foundation.
