I need to design a cooling tower for certain TR, is there any step by step procedure for cooling tower thermal design

Hi,

 

By Googling you would have many references for such requirement...

Hi ,

 

Plenty of information are available using the search engine in this forum .

 

Perry's chemical engineering handbook is also a good resource !

 

good luck!

Thank you sir. May I know whether any specific software is there for design of cooling tower. For instance: Thermal design of Heat exchangers - HTRI. Likewise cooling tower design has any software?

I don't think anybody designs a cooling tower himself, at least, I have never heard of it.

 

You specify what the cooling tower has to do and send that to a cooling tower vendor, who will then tell you what cooling tower type and size you need, what the plot space and height are, and what the cost is.

[PingPong]

In the real world cooling towers are only designed by a few engineers working at cooling tower vendors, using their company software.

 

I did not realise until now that this topic is posted under Student.

In addition to the suggestions of others, you should also look in

Volume 1 of Coulson & Richardson's Chemical Engineering

Volume 2 of Ludwig's Applied Process Design for Chemical and Petrochemical Plants

I agree with PingPong that it is usually only the engineers employed by cooling tower suppliers who do these calculations. It has only happened to me once where I needed to do such calculations myself, and that was where I needed to predict how a tower would function in summer from performance data taken during winter. There used to be a free DOS utility for cooling tower calcs available on this site, but it seems to have been taken down. DOS programs don't work under WIndows 7 and 8 anyway - I used it about 12 years ago.  There is a commercial equivalent for Windows available at http://www.engineeri...pr/sku27537.htm

 

Designing cooling towers from scratch makes no sense because you will not know the heat transfer factors of the packings - these are proprietary items.  In my case I was able to work from the winter perfomance data back to get the heat transfer factors and then use them to predict the summer performance. But I accept that was a very rare situation.
