Pls advice, the formula in order to calculate minimum area, velocity and heat transfer coefficient for helical baffle shell and tube heat exchanger.
thank you

Petronas:

You have to be residing in a fantasy world to believe that there is a "formula" - whether magical or secretive - that gives you all the information you are seeking.

Most, if not all of the information on Helical baffles and their results have been developed through proprietary methods requiring financial investment (which requires a net, resulting financial profit). As such, you would have to either work for those companies or develop your own technology. Just as you would never share your own technology with others, do not expect that others will share theirs with you. For example, Koch Heat Transfer's Heli-Baffle technology has been extensively tested at Heat Transfer Research , Inc. (HTRI) in a wide range of configurations including single and two-phase media and various baffle arrangments. The confirmed, definitive research data is the basis for KHT's ability to accurately predict performance and to eliminate your performance risk. The KHT (formerly Brown Fintube) design method embedded in HTRI Xchanger Suite 5.0 is the most advanced and accurate tool for design of Heli-Baffle exchangers. Empirical methods have been adequate for obtaining the design envelope, but frequently result in less than optimal designs

Petro,
If you are unwilling or unable to purchase the excellent HTRI Xchanger Suite software, then you can prepare a process datasheet(s) and submit it (them) to a helical baffle heat exchanger manufacturer and ask them to quote you their product that meets your criteria. If you are not very familiar with these calculations AND in possession of suitable tools (i.e. HTRI software), then you should not attempt the calcualtions you describe.

Thank you for your adv.
I have HTRI 5 and already used.
but now, I will made simulation software for the Helical Baffle Heat Exchanger and control it.
No Problem.

Thank you
